[PATCH 2/2] drm/i915/bios: Define the "luminance and gamma" sub-struct of block 46

[Ville Syrjala]

From: Ville Syrjälä <ville.syrj...@linux.intel.com>

Since BDB version 211 block 46 has included more luminance and
gamma related information. Define it fully. The data is semi-based
on DisplayID v2.0 apparently.
