SC7280 has VA, TX and RX macros with SoundWire Controllers to attach with
codecs like WCD938x, max98360a using soundwire masters and i2s bus.
Add these nodes for sc7280 based platforms audio use case.
Add tlmm gpio property in wcd938x node for switching CTIA/OMTP Headset.

You might want to consider splitting this patch into one that
adds the SoC specific bits and one for each board. It's cleaner
and might allow to land the SoC specific bits even when the board
specific part is still under discussion. It also might make the
life easier for folks who want to pick the SoC specific parts,
but aren't interested in the board bits (e.g. because they want
to support a different board). Just a thought, the split is not
strictly necessary.
Okay. will split accordingly.

This node shouldn't be at top but with the other device nodes, in
alphabetical order, i.e. before 'pwmleds'.
Actually we are sorting as per node name. Hence kept it here. As per
previous reviewer comments, sorted accordingly.
Please suggest better approach.
