drm/xe/lnl: Enable GuC SLPC DCC task
Enable DCC (Duty Cycle Control) in Lunar Lake.
DCC is the SLPC task that tries to keep
the GT from operating inefficiently when thermally constrained.
Although the recommendation is to enable it, LNL GuC is leaving
it disabled by default on LNL.
It would minimize the GT frequency oscillation on throttled
scenarios, which could potentially reduce latencies.
v2: Move set_policies call after wait for running state, so
we ensure it is not overwritten. (Vinay)
v3: Fix English in the commit message (Jonathan)
v4: Also set disable to 0 so DCC can really get into effect.
v5: Avoid lnl_ prefix (Vinay)
v6: Finish renaming...
