[Intel-gfx] [PATCH] Fix resume from suspend on IBM X30

[Thomas Richter]

Hi folks,

the attached patch fixes the resume from suspend on the IBM X30 (Bug
49838) by keeping a backup of the IVCH registers during initialization
and by replaying those values when re-setting a mode. The patch has been
successfully tested on an IBM X30 and on an IBM R31 laptop, both of
which make use of the same intel iVCH DVO.

Please let me know whether this patch is acceptable.

Thanks and have a nice weekend,

Thomas
