drm/edid: Handle EDID 1.4 range descriptor h/vfreq offsets
EDID 1.4 introduced some extra flags in the range
descriptor to support min/max h/vfreq >= 255. Consult them
to correctly parse the vfreq limits.
Note that some combinations of the flags are documented
as "reserved" (as are some other values in the descriptor)
but explicitly checking for those doesn't seem particularly
worthwile since we end up with bogus results whether we
decode them or not.
v2: Increase the storage to u16 to make it work (Jani)
Note the "reserved" values situation (Jani)
v3: Document the EDID version number in the defines
Drop some bogus (u8) casts
