Ville Syrjälä abc0b1447d drm: Perform basic sanity checks on probed modes
Make sure the timings of probed modes at least pass some very basic
sanity checks.

The checks include:
 - clock,hdisplay,vdisplay are non zero
 - sync pulse fits within the blanking period
 - htotal,vtotal are big enough

I have not checked all the drivers to see if the modes the generate
might violate these constraints. I'm hoping not, because that would mean
either abandoning the idea of doing this from the core code, or fixing
the drivers.

I'm not entirely sure about limiting the sync pulse to the blanking
period. Intel hardware doesn't support such things, but some other
hardware might. However at least HDMI doesn't allow having sync pulse
edges within the active period, so I'm thinking the check is probably
OK to have in the common code.
