Paulo Zanoni 90a8864320 drm/i915: set FORCE_ARB_IDLE_PLANES workaround ... Commit 1544d9d573 added a workaround inside haswell_init_clock_gating and mentioned it is "a workaround for early silicon revisions and should be removed later". This workaround is documented in bit 31 of PRI_CTL. I asked Arthur and he mentioned that setting FORCE_ARB_IDLE_PLANES replaces that workaround for the newer machines. So use the new one. Also notice that there's still another workaround for PRI_CTL that involves WM_DBG, but it's not the one we're reverting. And notice that we were previously setting WM_DBG_DISALLOW_MULTIPIPE_LP which disables the LP watermarks when more than one pipe is used, and we really don't want this because we need the LP watermarks if we want to reach deeper PC states.
