Add for the case that the registers are not kept in some low power modes. Signed-off-by: Jason Yu <zejiang.yu@nxp.com>

PINT connects GPIO pin to seperate IRQ slot. Add new API to get which IRQ slot is connected to, based on pin index. Signed-off-by: Jason Yu <zejiang.yu@nxp.com>

I'd like to know why the code needs to change?

I checked the usage of IS_ENABLED, the original implementation is the right way, will revert back.

same doxygen comments (compare with the .h) can remove.

return -EINVAL; is better maybe.

what about: When Power Management :kconfig:option:CONFIG_PM is enabled. add kconfig option makes the information clearer.

I'm not ok with this, since it will require adding the overlay on each app that will run with PM. I expect to have everything I need once I enable CONFIG_PM.
To avoid this lets set the os_timer status to okay by default in the nxp_mcxw23x_common.dtsi file, and change the MCUX_OS_TIMER redefinition in Kconfig.defconfig to:
config MCUX_OS_TIMER
- default y if PM
+ default n if !PM
This will allow to run on the CORTEX_M_SYSTICK when PM is not defined and switch to OS_TIMER when PM is enabled.
