drm/i915: Add enum aux_ch and clean up the aux init to use it
Since we no longer have a 1:1 correspondence between ports and AUX
channels, let's give AUX channels their own enum. Makes it easier
to tell the apples from the oranges, and we get rid of the
port E AUX power domain FIXME since we now derive the power domain
from the actual AUX CH.
v2: Rebase due to AUX F
v3: Split out the power domain fix (Rodrigo)
