drm/i915: reenable gmbus on gen3+ again
With the rework to merge the bit-banging fallback into the gmbus i2c adapter we've gotten rid of the deadlock possibility that originally lead to the disabling of this code. This reverts the revert commit 826c7e4147f902737b281e8a5a7d7aa33fd63316 Author: Jean Delvare <khali@linux-fr.org> Date: Sat Jun 4 19:34:56 2011 +0000 Revert "drm/i915: Enable GMBUS for post-gen2 chipsets" Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=35572 Reviewed-by: Eugeni Dodonov <eugeni.dodonov@intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
