[PATCH 38/51] drm/i915: Update some flush helpers to take request structures

[John.C.Harrison@xxxxxxxxx]

From: John Harrison <John.C.Harrison@xxxxxxxxx>

Updated intel_emit_post_sync_nonzero_flush(), gen7_render_ring_cs_stall_wa(),
gen7_ring_fbc_flush() and gen8_emit_pipe_control() to take requests instead of
rings.

For: VIZ-5115
