drm/i915: Sanitize PHY state during display core uninit
To work around a DMC/Punit issue on ICL where the driver's
ICL_PORT_COMP_DW8/IREFGEN PHY setting is lost when entering/exiting DC6
state, make sure to reinit the PHY whenever disabling DC states.
Similarly the driver's PHY/DBUF/CDCLK settings should have been preserved
across DC5/6 transitions, so check this on all platforms.
This gets rid of the following WARN during suspend:
Combo PHY A HW state changed unexpectedly
