[PATCH 1/2] drm/i915/guc/slpc: Enable GuC SLPC default strategies

[Rodrigo Vivi]

The Balancer and DCC strategies were left off on a fear that
these strategies would conflict with the i915's waitboost.
However, these strategies are only active in certain conditions where
the system is TDP limited. So, they don't conflict, but help the
waitboost by guaranteeing a bit more of GT frequency.

Without these strategies we were likely leaving some performance
behind on some scenarious.
