This patch series, adds support for analog audio on J721S2 EVM

Earlier version of the patchset sent upstream[0] was rejected as
its dependency[1], which resolves the DTBS check errors introduced
by [0] also got rejected on the grounds of ABI breakage.

Another solution to fix the DTBS check errors introduced by [0] is
to modify the ti,j721e-system-controller.yaml binding to allow
audio-refclk as clock-controller child. This is done in the first
patch of this series.
