drm/i915: Flush request queue when waiting for ring space
During the review of
commit 1f70999f9052f5a1b0ce1a55aff3808f2ec9fe42

drm/i915: Prevent recursion by retiring requests when the ring is full
Ville raised the point that our interaction with request->tail was
likely to foul up other uses elsewhere (such as hang check comparing
ACTHD against requests).
However, we also need to restore the implicit retire requests that certain
test cases depend upon (e.g. igt/gem_exec_lut_handle), this raises the
spectre that the ppgtt will randomly call i915_gpu_idle() and recurse
back into intel_ring_begin().

drm/i915/vlv: reset VLV media force wake request register
Media force wake get hangs the machine when the system is booted without
displays attached. The assumption is that (at least some versions of)
the firmware has skipped some initialization in that case.
Empirical evidence suggests we need to reset the media force wake
request register in addition to the render one to avoid hangs.
