From: Chandra Konduru <chandra.konduru@intel.com>

This patch adds NV12 to format_is_yuv() function
for sprite planes.

v2:
-Use intel_ prefix for format_is_yuv (Ville)

v3: Rebased (me)

v4: Rebased and addressed review comments from Clinton A Taylor.
"static function in intel_sprite.c is not available
to the primary plane functions".
Changed commit message - function modified for
sprite planes.

v5: Missed the Tested-by/Reviewed-by in the previous series
Adding the same to commit message in this version.

v6: Rebased (me)

v7: Rebased (me)

v8: Rebased (me)

v9: Rebased (me)

v10: Changed intel_format_is_yuv function from
static to non-static. We need to use it later from
other files for check.
