From: Tom O'Rourke <Tom.O'Rourke@intel.com>

If SLPC is to enabled, then set GUC_CTL_ENABLE_SLPC flag in GuC control
param GUC_CTL_FEATURE word during GuC load. This is required for early
SLPC init in GuC init path. SLPC gets enabled fully on sending this flag
during GuC load and on doing SLPC reset through Host to GuC action.

v1: Use intel_slpc_enabled() (Paulo)

v2-v4: Rebase.

v5: Changed intel_slpc_enabled() to i915.enable_slpc. (Sagar)

v6: Changed i915.enable_slpc to intel_slpc_enabled(). (Sagar)

v7: Rebase.

v8: Rebase.
