[Intel-gfx] [PATCH 06/16] drm/i915: Don't compute 5/6 DDB split w/ zero active pipes

[ville.syrjala at linux.intel.com]

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

When there are zero active pipes, all the watermarks should be zero
also. No point in wasting time w/ computing the 5/6 split watermark
config.
