drm/i915/guc: Enable DUAL_QUEUE_WA for newer platforms
For newer platforms (post DG2) hardware intentionally stalls on
submisstion of concurrent submissions on RCS and CCS of different
address spaces. With this workaround GuC will never schedule such
conlicting contexts; preventing detection of a stall as a hang.
GuC specs recommend to enable this for all platforms starting from MTL
supporting CCS.
v2: Use existing macros for version check. (Jani)
v3: Reword explanation for clarity. Remove unneeded parens. Remove
accidental comment change. (Daniele)
