Remove address-of operator ('&') when assigning `clock_control_xxx_init`
function pointer in `DEVICE_DT_INST_DEFINE` macro.
This change aims to maintain consistency among the drivers in
`drivers/clock_control`, ensuring that all function pointer assignments
follow the same pattern.

In order to bring consistency in-tree, migrate all drivers to the new
prefix <zephyr/...>. Note that the conversion has been scripted, refer
to #45388 for more details.

Refactors all of the clock control drivers to use a shared driver class
initialization priority configuration,
CONFIG_CLOCK_CONTROL_INIT_PRIORITY, to allow configuring clock control
drivers separately from other devices. This is similar to other driver
classes like I2C and SPI.
Most drivers previously used CONFIG_KERNEL_INIT_PRIORITY_OBJECTS or
CONFIG_KERNEL_INIT_PRIORITY_DEVICE, therefore the default for this new
option is the lower of the two, which means earlier initialization.
The even lower defaults for STM32 and Arm Beetle are preserved by
SoC-family level overrides.

Now that device_api attribute is unmodified at runtime, as well as all
the other attributes, it is possible to switch all device driver
instance to be constant.
A coccinelle rule is used for this:

Several reviewers agreed that DT_HAS_NODE_STATUS_OKAY(...) was an
undesirable API for the following reasons:
- it's inconsistent with the rest of the DT_NODE_HAS_FOO names
- DT_NODE_HAS_FOO_BAR_BAZ(node) was agreed upon as a shorthand
for macros which are equivalent to
DT_NODE_HAS_FOO(node) && DT_NODE_HAS_BAR(node) &&
- DT_NODE_HAS_BAZ(node), and DT_HAS_NODE_STATUS_OKAY is an odd duck
- DT_NODE_HAS_STATUS(..., okay) was viewed as more readable anyway
- it is seen as a somewhat aesthetically challenged name
Replace all users with DT_NODE_HAS_STATUS(..., okay), which is
semantically equivalent.
This is mostly done with sed, but a few remaining cases were done by
hand, along with whitespace, docs, and comment changes. These special
cases include the Nordic SOC static assert files.

Rename DT_HAS_NODE to DT_HAS_NODE_STATUS_OKAY so the semantics are
clear. As going forward DT_HAS_NODE will report if a NODE exists
regardless of its status.

move clock_control.h to drivers/clock_control.h and
create a shim for backward-compatibility.
No functional changes to the headers.
A warning in the shim can be controlled with CONFIG_COMPAT_INCLUDES.

These changes were obtained by running a script created by
Ulf Magnusson <Ulf.Magnusson@nordicsemi.no> for the following
specification:
1. Read the contents of all dts_fixup.h files in Zephyr
2. Check the left-hand side of the #define macros (i.e. the X in
#define X Y)
3. Check if that name is also the name of a Kconfig option
3.a If it is, then do nothing
3.b If it is not, then replace CONFIG_ with DT_ or add DT_ if it
has neither of these two prefixes
4. Replace the use of the changed #define in the code itself
(.c, .h, .ld)
Additionally, some tweaks had to be added to this script to catch some
of the macros used in the code in a parameterized form, e.g.:
- CONFIG_GPIO_STM32_GPIO##__SUFFIX##_BASE_ADDRESS
- CONFIG_UART_##idx##_TX_PIN
- I2C_SBCON_##_num##_BASE_ADDR
and to prevent adding DT_ prefix to the following symbols:
- FLASH_START
- FLASH_SIZE
- SRAM_START
- SRAM_SIZE
- _ROM_ADDR
- _ROM_SIZE
- _RAM_ADDR
- _RAM_SIZE
which are surprisingly also defined in some dts_fixup.h files.
Finally, some manual corrections had to be done as well:
- name##_IRQ -> DT_##name##_IRQ in uart_stm32.c

The mcux sim clock control driver was originally designed to pass
through the clock subsystem value from dts to the mcux CLOCK_GetFreq()
function. This assumed that the values in
include/dt-bindings/clock/kinetis_sim.h matched the enumeration in
fsl_clock.h, which is true for the coresys, platform, and bus clocks.
However, the low-power oscillator (LPO) clock has a different values in
k64 vs. kw2xd, therefore we must update the clock_control driver to
parse the value from dts and convert it to the fsl_clock.h enumeration.

Adds a new clock control driver for Kinetis SoCs that have the system
integration (SIM) module. This will allow mcux shim drivers, such as
uart and i2c, to abstract the call to CLOCK_GetFreq() behind the
clock_control interface and thus be reused for SoCs with different clock
architectures.
