Imre Deak 602438ead3 drm/i915/icl: Fix port B combo PHY context loss after DC transitions
On ICL DMC/PCODE retains the HW context only for port A across DC
transitions, for the other port B combo PHY, it doesn't. So we need to
do this manually after exiting from DC6. Do the reinit even after
exiting from DC5, it won't hurt since we only reinit the PHY in case
it's needed (in case it was disabled to begin with).

As can be guessed from the bugzilla report leaving the PHY uninited will
lead to a later timeout during the port B specific AUX and DDI_IO power
well enabling.

v2:
- Apply the fix on all GEN>=11 platforms. (Rodrigo)
