The ti,j721e-system-controller binding currently only allows
clock-controller@ child nodes to reference the ti,am654-ehrpwm-tbclk
schema. However, the system controller on J721S2 also contains audio
reference clock controllers (ti,am62-audio-refclk) that use the same
clock-controller@XXXX naming pattern.

Hence, extend the clock-controller pattern to accept either ehrpwm-tbclk
or audio-refclk schemas using a oneOf constraint.

J721S2 or AM62?

Alphanumerical order.

There is no ti,am62 in the top level compatibles, so why am62 is here?
Top level has j721s2 but this ti,am62-audio-refclk.yaml only am62.
