Subject: [PATCH 26/37] dt-bindings: clock: apple,nco: Add t6020-nco
 compatible

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

The block found on Apple's M2 Pro/Max/Ultra SoCs is compatible with
"apple,t8103-nco" so add its per-SoC compatible with the former as
fallback used by the existing driver.
