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.
