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: Use generic struct data to describe pin function

Replace struct s32_pmx_func with generic struct pinfunction since they
have the same data fields.

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].
