Add bindings for the MT7981 pinctrl driver. As MT7981 has most features
in common with MT7986 (but has a different layout in terms on pinctrl
and clocks), the existing mediatek,mt7986-pinctrl.yaml was used as an
example to create a similar document covering MT7981.

Qualcomm pinctrl Devicetree bindings changes for v6.3

Set of cleanups and fixes for Qualcomm pin controller bindings, to match
existing DTS and correct the schema.

AT91 pinctrl deferred probing support is broken if the GPIO devices
haven't probed first and set gpio_banks to non-zero. The later condition
that only some GPIO devices haven't probed can't actually happen as
either all the GPIO devices have probed first or none of them have. Plus
the pinctrl driver has already returned -EINVAL, so it's not on the
deferred list to retry probing.

Fix this by consolidating the checking that all GPIO devices are probed.

ambiguous because any prefix or suffix is allowed. If that's desired, it
