drm/i915/glk: Fix degamma lut programming
Fixed the glk degamma lut programming which currently
was hard coding a linear lut all the time, making degamma
block of glk basically a pass through.
Currently degamma lut for glk is assigned as 0 in platform
configuration. Updated the same to 33 as per the hardware
capability. IGT tests for degamma were getting skipped due to
this, spotted by Swati.
ToDo: The current gamma/degamm lut ABI has just 16bit for each
color component. This is not enough for GLK+, since input
precision is increased to 3.16 which will need 19bit entries.
v2: Added Matt's RB.
v3: Changed uint32_t to u32.
v4: Fixed Maarten's review comment
