gpio: nomadik: support mobileye,eyeq5-gpio
We create a custom compatible for the STA2X11 IP block as integrated
into the Mobileye EyeQ5 platform. Its wake and alternate functions have
been disabled, we want to avoid touching those registers.
We both do: (1) early return in functions that do not support the
platform, but with warnings, and (2) avoid calling those functions in
the first place.
We ensure that pinctrl-nomadik is not used with this STA2X11 variant.
