drm/i915: Do not read GAMMA_MODE register
Implement Daniel Stone's recommendation to not read registers to infer
the hardware's state.
v2: Read GAMMA_MODE register value at init (Matt Roper's comment)
v3: Read GAMMA_MODE register in intel_modeset_readout_hw_state along
with other registers (Matt Roper's comment).
v4: Mask GAMMA_MODE register with interesting bits when reading
