When SSR/PDR occurs during record usecase, swr dmic's need
to be shutdown before WCD938x is set to reset low, since swr dmic's
depend on WCD938x for mic bias.
The swr dmic's are shutdown from sound wire master
control during SSR/PDR via driver ops, before WCD938x is shutdown.

after a successful dmic probe.

Soundwire DMICs provide the same quality as regular DMICs but
the interface is soundwire. This reduces the number of pins
on the MSM. Enable soundwire DMICs on lahaina.

Supply for swr dmic is from wcd mic bias.
Enable the power supply by calling corresponding
interfaces from cdc supply driver.

Add initial changes for supporting swr dmic
where each codec can support single mic recording
over soundwire port.
