pinctrl: Explicitly include correct DT includes

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

pinctrl: s32: separate const device data from struct s32_pinctrl_soc_info

The .data field in struct of_device_id is used as a const member so it's
inappropriate to attach struct s32_pinctrl_soc_info with of_device_id
because some members in s32_pinctrl_soc_info need to be filled by
pinctrl-s32cc at runtime.

For this reason, struct s32_pinctrl_soc_info must be allocated in
pinctrl-s32cc and then create a new struct s32_pinctrl_soc_data in order
to represent const .data in of_device_id. To combine these two structures,
a s32_pinctrl_soc_data pointer is introduced in s32_pinctrl_soc_info.

Besides, use of_device_get_match_data() instead of of_match_device() since
the driver only needs to retrieve the .data from of_device_id.

pinctrl: s32cc: fix !CONFIG_PM_SLEEP build error

The declaration of s32_pinctrl_suspend/s32_pinctrl_resume is hidden
in an #ifdef, causing a compilation failure when CONFIG_PM_SLEEP is
disabled:

drivers/pinctrl/nxp/pinctrl-s32g2.c:754:38: error: 's32_pinctrl_suspend' undeclared here (not in a function); did you mean 's32_pinctrl_probe'?
drivers/pinctrl/nxp/pinctrl-s32g2.c:754:9: note: in expansion of macro 'SET_LATE_SYSTEM_SLEEP_PM_OPS'
754 | SET_LATE_SYSTEM_SLEEP_PM_OPS(s32_pinctrl_suspend,
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~

Remove the bogus #ifdef and __maybe_unused annation on the global
functions, and instead use the proper LATE_SYSTEM_SLEEP_PM_OPS()
macro to pick set the function pointer.

As the function definition is still in the #ifdef block, this leads
to the correct code in all configurations.

pinctrl: add NXP S32 SoC family support

Add the pinctrl driver for NXP S32 SoC family. This driver is mainly based
on NXP's downstream implementation on nxp-auto-linux repo[1].
