drm/edid: Add support for quirks visible to DRM core and drivers
Add support for EDID based quirks which can be queried outside of the EDID parser iteself by DRM core and drivers. There are at least two such quirks applicable to all drivers: the DPCD register access probe quirk and the 128b/132b DPRX Lane Count Conversion quirk (see 3.5.2.16.3 in the v2.1a DP Standard). The latter quirk applies to panels with specific EDID panel names, support for defining a quirk this way will be added as a follow-up. v2: Reset global_quirks in drm_reset_display_info(). v3: (Jani) - Use one list for both the global and internal quirks. - Drop change for panel name specific quirks. - Add comment about the way quirks should be queried.
