Matthew Brost b1231ff7ea drm/xe: Mark ComputeCS read mode as UC on iGPU ...

RING_CMD_CCTL read index should be UC on iGPU parts due to L3 caching
structure. Having this as WB blocks ULLS from being enabled. Change to
UC to unblock ULLS on iGPU.

v2:
 - Drop internal communications commnet, bspec is updated
