drm/i915: Init HSW watermark tracking in intel_modeset_setup_hw_state()
Fill out the HSW watermark s/w tracking structures with the current
hardware state in intel_modeset_setup_hw_state(). This allows us to skip
the HW state readback during watermark programming and just use the values
we keep around in dev_priv->wm. Reduces the overhead of the watermark
programming quite a bit.
v2: s/init_wm/wm_get_hw_state
Remove stale comment about sprites
