[Intel-gfx] [PATCH v2 00/25] vlv: add support for RPM

[Imre Deak]

For a description of this patchset see the previous cover letter [1].

Tested on HSW (non-ULT), VLV with igt/kms_flip and pm_pc8.

v2:
- addressed comments about getting the proper runtime PM references in
  debugfs (Daniel, Paulo, Ville)
- disable RPM if RC6 is disabled for all platforms, not just VLV
  (Daniel)
- refactored the runtime PM callbacks pulling platform independent
  teardown/re-init code to the generic runtime suspend/resume callbacks
  (Daniel)
- fixed a couple of issues I bumped into while checking the RC6/RPS
  and the GPU reset error capturing path
