[PATCH 11/14] drm/i915: Make intel_bw_check_sagv_mask() internal to intel_bw.c

[Ville Syrjala]

From: Ville Syrjälä <ville.syrj...@linux.intel.com>

The only thing between the current intel_bw_check_sagv_mask() call
site and intel_bw_atomic_check() is skl_wm_add_affected_planes()
which no longer depends on the sagv mask, so we can make life
a lot less confusing by calling intel_bw_check_sagv_mask() from
intel_bw_atomic_check() instead.
