[PATCH 04/14] drm/i915: Pass intel_dbuf_bw to skl_*_calc_dbuf_bw() explicitly

[Ville Syrjala <ville.syrjala@xxxxxxxxxxxxxxx>]

From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>

Make skl_*_calc_dbuf_bw() a bit lower level passing in the
to be mutated dbuf_bw struct in explicitly. This will allow
more reuse later.
