Subject: [PATCH] clk: clk-apple-nco: Add "apple,t8103-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.

Fixes: 6641057d5dba ("clk: clk-apple-nco: Add driver for Apple NCO")

This is split off from the v1 series adding Apple M2 Pro/Max/Ultra
device trees in [2].

Changes compared to that series:
- add "Fixes:" and "Cc: stable" for handling this as fix adding a device
  id
- add Neal's and Stephen's trailers
