…inux into drm-fixes

Two regression reverts, and two fixes, one for a dpm boot freeze.

* 'drm-fixes-4.1' of git://people.freedesktop.org/~agd5f/linux:
  drm/radeon: Make sure radeon_vm_bo_set_addr always unreserves the BO
  Revert "drm/radeon: adjust pll when audio is not enabled"
  Revert "drm/radeon: don't share plls if monitors differ in audio support"
  drm/radeon: fix freeze for laptop with Turks/Thames GPU.
