Subject: [PATCH 02/37] dt-bindings: arm: apple: apple,pmgr: Add t6020-pmgr
 compatible

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

The block on Apple M2 Pro/Max/Ultra SoCs is compatible with
"apple,t8103-pmgr" so use it as fallback compatible and add t6020 as
per-SoC compatible.
