drm/i915: Add limited color range readout for HDMI/DP ports on g4x/vlv/chv
The limited color range knob is in the port registers on
g4x and vlv/chv for HDMI, and on g4x for DP. Add the relevant code
to read out the hardware state into pipe config. On vlv/chv the
DP port limited color range knob is in PIPECONF for which we
already have readout code.
