drm/i915: Introduce g4x_dp.c
Move the g4x+ DP code into a new file. This will leave mostly
platform agnostic code in intel_dp.c. Well, the misplaced phy
test stuff pretty much ruins that, but let's squint real hard
for now.
v2: Add comment exlaining which platforms are covered (Daniel)
Leave intel_dp_unused_lane_mask() be since it is pretty generic
