drm/i915/icl: Enable Sampler DFR
Sampler Dynamic Frequency Rebalancing (DFR) aims to reduce Sampler
power by dynamically changing its clock frequency in low-throughput
conditions. This patches enables it by default on Gen11.
v2: Wrong operation to clear the bit (Praveen)
v3: Rebased on top of the WA refactoring
v4: Move to icl_init_clock_gating, since it's not a WA (Rodrigo)
v5: C, not lisp (Chris)
