drm/i915/gt: Use XY_FASR_COLOR_BLT to clear obj on graphics ver 12+
XY_FAST_COLOR_BLT cmd is faster than the older XY_COLOR_BLT. Hence for clearing (Zero out) the pages of the newly allocated object, faster cmd is used. Signed-off-by: Ramalingam C <ramalingam.c@intel.com> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
