drivers: pinctrl: rename nxp,kinetis-pinctrl to nxp,port-pinctrl

The NXP PORT pinmuxing peripheral is reused across the MCX, S32, and
Kinetis lines. Rename the compatible from the family-specific
nxp,kinetis-pinctrl to a more generic nxp,port-pinctrl to reflect the
actual name for the IP block used within reference manuals.

Update the NXP HAL revision to include a change to use the new Kconfig
name for the PORT pinctrl driver

Update the MAINTAINERS.yml path, as there are no longer any NXP drivers
matching the string "drivers/*/*kinetis*
