[Intel-gfx] [PATCH 2/2] drm/i915/icl: Whitelist GEN9_SLICE_COMMON_ECO_CHICKEN1

[Chris Wilson]

From: Tvrtko Ursulin <tvrtko.ursulin at intel.com>

WaEnableStateCacheRedirectToCS context workaround configures the L3 cache
to benefit 3d workloads but media has different requirements.

Whitelist the register to allow media re-configuring it to their liking.
