drm/i915/psr: New power domain for AUX IO.
PSR on CNL requires AUX IO wells to be kept on and the existing AUX domain
for AUX-A enables DC_OFF well too. This is not required, so add a new
AUX_IO_A domain for AUX-A to allow DC states to remain enabled. Other AUX
channels re-use the existing AUX domains.
v4: Reword comment (Rodrigo and Ville)
Rename _get and _put functions to include aux_io substring(Rodrigo)
Remove unnecessary diff that got included.
v3: Extract aux domain selection into a function (Ville)
v2: Add AUX IO domain only for AUX-A
Rebased on top of Ville's AUX series.
