drm: edid revision 0 is valid
edid->revision == 0 should be valid (at least, so the error message
indicates. :) and wikipedia seems to indicate that EDID 1.0 existed.
We can dump the entire check, since edid->revision is a u8, so
it can't ever be less than 0.
Marko reports in RH bz#476735 that his monitor claims to be
EDID 1.0, and therefore hits the check and is stuck at 800x600 because
of it.
