[PATCH v4 1/2] dt-bindings: ti: Update audio-refclk binding and j721e system controller

[Moteen Shah]

Add ti,j721s2-audio-refclk as a supported compatible string in the
ti,am62-audio-refclk binding. J721S2 uses the same audio reference
clock IP block first introduced on AM62. Per writing-bindings
guidelines, the J721S2-specific compatible is added as the primary
string with ti,am62-audio-refclk as the fallback.

Also extend the ti,j721e-system-controller clock-controller@ child
pattern to accept audio-refclk schemas alongside ehrpwm-tbclk via a
oneOf constraint, fixing the alphanumerical ordering of $refs.
