[Intel-gfx] [PATCH 00/15] vlv: add support for RPM

[Imre Deak]

This adds the required helpers for saving/restoring HW context when
going to D3 (and possibly to S0ix afterwards) state on VLV and then
enables RPM.

Since we depend on the RC6 power context mechanism to save some state
this also touches generic RPM parts, so that RPM is only enabled after
the delayed RC6 enabling completes.

For more details on the VLV specific parts see patches 13 and 14.

I also included a related bugfix that Daniel and Paulo were also looking
at (patch 7).

I tested this with igt/kms_flip and pm_pc8 on VLV/DP, they seem to pass
fine, although I'm not sure that pm_pc8 goes through all interesting
paths, I'm planning to check this next.
