drm/edid: Add packed attribute to new gtf2 and cvt structs
The new structs added in struct detailed_data_monitor_range must be marked with packed attribute although the outer struct itself is already marked as packed. Otherwise these 7-bytes structs may be aligned, and give the wrong position and size for the data.
