Ville Syrjälä caed361d83 drm/i915: Fix watermarks for VLV/CHV ... commit 92826fcdfc ("drm/i915: Calculate watermark related members in the crtc_state, v4.") broke thigns by removing the pre vs. post wm update distinction. We also lost the pre plane wm update entirely for VLV/CHV from the crtc enable path. This caused underruns on modeset and plane enable/disable on CHV, and often those can lead to a dead pipe. So let's bring back the pre vs. post thing, and let's toss in an explicit wm update to valleyview_crtc_enable() to avoid having to put it into the common code. This is more or less a partial revert of the offending commit.
