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.] Signed-off-by: Alex Deucher <alexdeucher@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
