[Intel-gfx] [PATCH 2/7] drm/i915: implement a media hang w/a

Contrary to the other clock gating w/a in GEN6_UCGCTL1, this one is actually documented in Bspec, vol1g "GT Interface Registers [SNB]", Section 1.5.1 "UCGCTL1 - Unit Level Clock Gating Control 1". Supposedly this can prevent hangs on the media ring. Signed-Off-by: Daniel Vetter --- drivers/gpu/
