Add the "google,gs101-pinctrl" compatible to the dt-schema bindings
documentation.

Add maxItems of 50 for the interrupts property as gs101 can have
multiple irqs.

These are external wakeup interrupts.

Looking again I believe this can be dropped entirely as re-reading
samsung,pinctrl-gpio-bank.yaml we are already defining the
external wake-up interrupts on each bank in gs101-pinctrl.dtsi.

It isn't variable.
