drm/radeon/kms: add support for hardcoded edids in rom (v2)
Some servers hardcode an edid in rom so that they will
work properly with KVMs. This is a port of the relevant
code from the ddx.
[airlied: reworked to validate edid at boot stage - and
remove special quirk, if there is a valid EDID in the BIOS rom
we'll just try and use it.]
