Previously, dtlib would fail to parse the following:
/delete-node/ &{/};
This is accepted by dtc, so dtlib should be aligned.
The expected behavior is that the contents of the "deleted" root node
are emptied, but the node itself remains in the tree. This means that
it's possible to put that statement at the end of a DTS file and still
get a valid output. A small test case for this scenario is included.

Make sure filters set by property-allowlist and property-blocklist
in an including binding are recursively applied to included bindings.
Signed-off-by: Christophe Dufaza <chris@openmarl.org>
Although the PropertySpec.path attribute is documented as
"the file where the property was last modified",
all property specs in Binding.prop2specs will claim
they were last modified by the top-level binding itself.
Consider:
- I1 is a base binding that specifies properties x and y
- I2 is an "intermediate" binding that includes I1,
modifying the specification for property x
- B is a top-level bindings that includes I2,
and specifies an additional property p
When enumerating the properties of B,
we expect the values of PropertySpec.path to tell us:
- y was last modified by I1
- x was last modified by I2
- p was last modified by B
However, the Binding constructor:
- first merges all included bindings into the top-level one
- eventually initializes specifications for all the defined properties
As a consequence, all defined properties claim they were last modified
by the top-level binding file.
We should instead:
- first, take into account their own specifications for the
included properties
- eventually update these specifications with the properties
the top-level binding adds or modifies

The current EDT graph logic only use properties directly under a
specific node to add dependencies. For nodes properties in
child-bindings, this means that the child phandles are only linked by
the child node itself, which does have an ordinal but no corresponding
"sturct device" in the code, causing those dependencies to be silently
ignored by gen_handles.py.
Fix that by adding the recursive logic to visit child bindings when
present, which causes all child node property handles to be linked to
the parent node.

When we have an empty Devicetree, ie,
```
/dts-v1/;
/ {
};
```
The node's dep_ordinal is never initialized because the node graph is
empty. This ends up with invalid ordinal tokens (-1) in
devicetree_generated.h which in turn produce some cryptic compiler
errors, see e.g.
```
error: pasting "dts_ord_" and "-" does not give a valid preprocessing

In Linux, checkpatch.pl relies on the vendor-prefixes.yaml file
to validate manufacturers in compatible strings.
In addition to the vendors defined in vendor-prefixes.txt,
the YAML file includes expressions for "prefixes which are not vendors":
these expressions do NOT define special manufacturers that may appear
in compatible strings, and are never involved as such in DTS files.
We can rather see them as bulk-definitions of JSON/YAML properties
suitable for the dt-schema tools.
OTHO, in Zephyr, checkpatch.pl relies on the vendor-prefixes.txt file,
which does not include these additional prefixes, but edtlib.EDT adds
them as hard-coded special values.
This is confusing, if not incorrect:
- the fact that edtlib.EDT (and thus its client code in the
zephyr/scripts directory) actually allows these vendors
in compatible strings is buried in the source code
- checkpatch.pl (with vendor-prefixes.txt) in Zephyr behaves neither like
checkpatch.pl (with vendor-prefixes.yaml) in Linux, nor like edtlib.EDT
(with _VENDOR_PREFIX_ALLOWED)
- Zephyr should not treat these "prefixes which are not vendors" as
valid manufacturers in compatible strings to begin with

This is a one-line fix for edtlib, which lets gen_defines.py indicate
whether the `ranges` property exists within a given node.
Although address translation through ranges is typically automatic,
users can choose to manually inspect ranges using DT_FOREACH_RANGE(),
DT_NUM_RANGES(), and other DT_RANGES_* macros. These can be used to
implement manual translation at runtime, which is currently done for
PCIe controllers.
The only thing missing is being able to check if a node contains an
empty `ranges;`, which signifies a 1:1 translation to the parent bus.
Checking DT_NUM_RANGES() is insufficient, because it returns zero
whether or not `ranges;` is present.
It should be possible to use DT_NODE_HAS_PROP(), but it was not working,
because edtlib ignores properties which are undeclared in bindings and
don't have a default type. Add a missing PropertySpec for `ranges` with
"compound" type; it can't be "array" because it can be empty-valued.

Just like we did for dtlib in 15e3e317f7
("dtlib: implement copy.deepcopy() for DT"), except this time it's for
EDT. This also can do no harm and will be useful for implementing
system devicetree support.
No functional changes expected under the assumption that no users are

properties, these are not phandle-arrays as they only carry the data part
(e.g. pin, flags) but lack the phandles to the (parent) GPIO controller.

Inconsistency between python-devicetree version numbers
may be confusing:
- the last version at PyPI is 0.0.2
- zephyr-rtos/python-devicetree/setup.py sets the version
to 0.0.2 (this is probably the setup file used when uploading
to PyPI)
- zephyr-rtos/zephyr/scripts/dts/python-devicetree/setup.py sets
the version to 0.0.1
This may suggest that the mirror repository, and PyPI, are more
up-to-date than zephyr-rtos/zephyr/scripts/dts/python-devicetree.
Repositories being otherwise mostly identical (1), also bumping
the python-devicetree's version here seems a sane option.

This is essentially a revert of PR #46311 "python-devicetree: CI hotfix",
assuming the original issue has been resolved, either upstream in
types-PyYAML or in Zephyr itself.
Tested with types-PyYAML 6.0.12.2 (current version at PyPI):
$ python -m mypy --config-file=tox.ini --package=devicetree
dtlib.py:962: note: By default the bodies of untyped functions [...]
dtlib.py:964: note: By default the bodies of untyped functions [...]
dtlib.py:965: note: By default the bodies of untyped functions [...]
dtlib.py:967: note: By default the bodies of untyped functions [...]
Success: no issues found in 4 source files
The "notes" above are harmless (use of type hinting to define local
variables while mypy won't "check the bodies of untyped functions").
