On Lenovo ThinkPad T14s, the headset is connected via a HiFi Switch to
support CTIA and OMTP headsets. This switch is used to minimise pop and
click during headset type switching.

This patchset adds required bindings and changes to codec and dts to   
tnable the regulator required to power this switch along with wiring up
gpio that control the headset switching.

Without this patchset, there will be lots of noise on headset and mic
will not we functional.
