drm/i915: Avoid taking the PPS lock for non-eDP/VLV/CHV
On ICL we have to make sure that we enable the AUX power domain in a
controlled way (corresponding to the port's actual TypeC mode). Since
the PPS lock - which takes an AUX power ref - is only needed on
eDP on all platforms and eDP/DP on VLV/CHV avoid taking it in all
other cases.
v2:
- Clarify commit log about the condition for taking the PPS lock.
