This patch set splits out static hdr metadata backlight range parsing
from gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c into gpu/drm/drm-edid.c
as a new function. This new function is then used during edid parsing
when HDR static metadata block parsing.
Calculated values are stored in a new struct drm_luminance_range
introduced into display_info. Amdgpu_dm.c and intel_dp_aux_backlight.c
are using this new data.
v3: Some clean-ups suggested by Jani Nikula
v2: Calculate the range during edid parsing and store into display_info

drm: New function to get luminance range based on static hdr metadata
drm/amdgpu_dm: Rely on split out luminance calculation function
drm/i915: Use luminance range calculated during edid parsing
