[PATCH 19/37] dt-bindings: mfd: apple,smc: Add t6020-smc compatible

[Janne Grunau]

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

SMC on Apple's M2 Pro/Max/Ultra SoCs is compatible with the existing
driver so add its per-SoC compatible with the new base compatible as
fallback used by the driver.
