[Intel-gfx] [PATCH v2 01/17] drm/i915: Add scaled paramater to update_sprite_watermarks()

From: Ville Syrjälä <ville.syrjala at linux.intel.com>
For calculating watermarks we want to know whether sprites are
scaled. Pass that information to update_sprite_watermarks() so that
eventually we may do some watermark pre-computing.
v2: Use "enabled" consistently, fix commit msg
