This commit catch the return code of the spi_config function and
early returns on error so that high level spi transfer api gets
the error too.

This commit adds support for configuring SPI frequency per transaction.
The "clock-frequency" devicetree property is used as the default
frequency unless the peripheral being communicated with has a lower
"max-spi-frequency" (passed to the driver as spi_config::frequency).
An error is returned if the requested frequency is higher than the
hardware can support. This limit is half the peripheral clock (PCLK on
Series 2, HFPERCLK on Series 0/1) for SPI in controller mode.
Previously, the driver hard-coded 1 MHz operation. For backwards
compatibility, default to 1 MHz if the "clock-frequency" property is not
set in devicetree.

This commit adds support for devices such as EFR32xG24 in the SPI
driver, as these devices only have a single USART peripheral.

This change marks each instance of the 'spi_driver_api' as 'static const'.
The rationale is that 'spi_driver_api' is used for declaring internal
module interfaces and is not intended to be modified at runtime.
By using 'static const', we ensure immutability, leading to usage of only
.rodata and a reduction in the .data area.

This commit makes the peripheral-id property optional and removes it's
usage from the Gecko SPI driver.

This commit updates the Gecko SPI driver to reflect the

In case when we have multiple devices connected to the
one SPI interface the initial state of CS gpios after
MCU reset is floating and it might be low that prevents us from
communicating between particular devices. Fix that by
initializing all provided cs gpios and setting them as inactive.

Now that device_api attribute is unmodified at runtime, as well as all

Usually, we want to operate only on "available" device
nodes ("available" means "status is okay and a matching binding is
found"), but that's not true in all cases.
Sometimes we want to operate on special nodes without matching
bindings, such as those describing memory.
To handle the distinction, change various additional devicetree APIs
making it clear that they operate only on available device nodes,
adjusting gen_defines and devicetree.h implementation details
accordingly:
- emit macros for all existing nodes in gen_defines.py, regardless
of status or matching binding
- rename DT_NUM_INST to DT_NUM_INST_STATUS_OKAY
- rename DT_NODE_HAS_COMPAT to DT_NODE_HAS_COMPAT_STATUS_OKAY
- rename DT_INST_FOREACH to DT_INST_FOREACH_STATUS_OKAY
- rename DT_ANY_INST_ON_BUS to DT_ANY_INST_ON_BUS_STATUS_OKAY
- rewrite DT_HAS_NODE_STATUS_OKAY in terms of a new DT_NODE_HAS_STATUS
- resurrect DT_HAS_NODE in the form of DT_NODE_EXISTS
- remove DT_COMPAT_ON_BUS as a public API
- use the new default_prop_types edtlib parameter

Remove semicolon between instance invocations of DT_FOREACH_IMPL_ and
thus DT_INST_FOREACH. This provides more flexibility to the user. This
requires we fixup in tree users to add semicolon where needed.
