The coarse power gating was disabled as part of commit 2248a28384fe ("drm/i915/gen8+: Add RC6 CTX corruption WA") as a prelude to recover from the context corruption; the power gating itself has no direct impact on the RC6 context corruption. However, that recovery scheme was never implemented due to difficult corner cases, and so we no longer need to keep the power gating disabled.
