    drm/i915: Replace pcu_lock with sb_lock

    We now have two locks for sideband access. The general one covering
    sideband access across all generation, sb_lock, and a specific one
    covering sideband access via the punit on vlv/chv. After lifting the
    sb_lock around the punit into the callers, the pcu_lock is now redudant
    and can be separated from its other use to regulate RPS (essentially
    giving RPS a lock all of its own).

    v2: Extract a couple of minor bug fixes.
