[PATCH] Enable probing of non-rb modes

With the current implementation of collecting edid modes,
in case rb mode exists for a non rb mode of same resolution and 
vrefresh, the non-rb mode is never fed to display controller to be
probed, as a result we lose on using the non-rb mode, if the display 
controller does not support rb mode but supports non-rb.


For instance in case of 1680x1050 at 60Hz:
with monitor whose EDID supports RB,
if connected to  display controller does not support 1680x1050 at 60Hz RB but it 
supports 1680x1050 at 60Hz, with the current implementation the non-rb mode
1680x1050 at 60Hz is not listed in connectors probed modes and hence on running 
xrandr is not listed.

  drm: edid: enable probing and listing of non rb modes
