drm: New function to get luminance range based on static hdr metadata
Split luminance min/max calculation using static hdr metadata from
drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c:update_connector_ext_caps
into drm/drm_edid.c and use it during edid parsing. Calculated range is
stored into connector->display_info->luminance_range.
Add new data structure (drm_luminance_range_inf) to store luminance range
calculated using data from EDID's static hdr metadata block. Add this new
struct as a part of drm_display_info struct.
v3: Squashed adding drm_luminance_range_info patch here
v2: Calculate range during edid parsing
