These 3 patches add the support to enable audio on J721S2-EVM.

This required the i2c-mux support[0] which is now in linux tree.

Now, this series ***depends upon only one dts change[1]*** to ensure there
are no dtbs_check warnings (no functional issues):
"ti,j721e-system-controller.yaml" refers to "ti,am654-ehrpwm-tbclk.yaml"
for clock-controller nodes, but for audio we need "ti,am62-audio-refclk".
When scm_conf is "simple-bus", there are no such warnings.
