Subject: [PATCH 09/37] dt-bindings: pinctrl: apple,pinctrl: Add
 apple,t6020-pinctrl compatible

After discussion with the devicetree maintainers we agreed to not extend
lists with the generic compatible "apple,pinctrl" anymore [1]. Use
"apple,t8103-pinctrl" as fallback compatible as it is the SoC the driver
and bindings were written for.

The M2 Pro/Max/Ultra SoCs use the same pinctrl hardware, so just add its
per-SoC compatible using the new base as fallback.
