[PATCH 12/14] drm/i915: Make intel_bw_modeset_checks() internal to intel_bw_atomic_check()

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

Now that all the sagv computation has been moved from the
skl+ watermark code into intel_bw_atomic_check() there is
no point in calling intel_bw_modeset_checks() before the
wm computation. Hide it within intel_bw_atomic_check().
