commit 65ca7514e21adbee25b8175fc909759c735d00ff
Author: Damien Lespiau <damien.lespiau@xxxxxxxxx>
Date: Mon Feb 9 19:33:22 2015 +0000
drm/i915/skl: Implement WaBarrierPerformanceFixDisable
got misapplied and the code landed in chv_init_workarounds() instead of
the intended skl_init_workarounds(). Move it over to the right place.
