Jani Nikula f1a2f5b7c5 drm/i915: fall back to bit-banging if GMBUS fails in CRT EDID reads 
GMBUS was enabled over bit-banging as the default in commits:

commit c3dfefa0a6
Author: Daniel Vetter <daniel.vetter@ffwll.ch>
Date:   Tue Feb 14 22:37:25 2012 +0100

    drm/i915: reenable gmbus on gen3+ again

and

commit 0fb3f969c8
Author: Daniel Vetter <daniel.vetter@ffwll.ch>
Date:   Fri Mar 2 19:38:30 2012 +0100

    drm/i915: enable gmbus on gen2

Unfortunately, GMBUS seems to fail on some CRT displays. Add a bit-banging
fallback to CRT EDID reads.
