Just posting this so it's on the ML.
NAK on this patch, this causes leftover cursors on SKL. Additionally, there's a
noticeable lag every time I move the cursor from one monitor to another, and the
flickering from the broken watermarks still happens.

When we write watermark values to the hardware, those values are stored
in dev_priv->wm.skl_hw. However with recent watermark changes, the
results structure we're copying from only contains valid watermark and
DDB values for the pipes that are actually changing; the values for
other pipes remain 0
