[Intel-gfx] Updated drm-intel-testing

[Daniel Vetter]

Hi all,

So apparently I've failed to send the -testing update mail last Friday.
But that tree turned out to be seriously broken anyway, so seems I've been
lucky. Anyway, a big one with quite some patches:
- more hangcheck work from Mika and Chris to prepare for arb robustness
- trickle feed fixes from Ville
- first parts of the shared pch pll rework, with some basic hw state
  readout and cross-checking
- Haswell audio power well support from Wang Xingchao (alsa bits acked by
  Takashi)
- some cleanups and asserts sprinkling around the plane/gamma enabling
  sequence from Ville
- more gtt refactoring from Ben
- clear up the adjusted->mode vs. pixel clock vs. port clock confusion
- 30bpp support, this time for real hopefully


Happy testing!

Cheers, Daniel
