[igt-dev] [PATCH i-g-t] [i-g-t] tests/kms_plane_scaling: Change minimum fb height for YUV 420 planar

When the plane scaling is used with YUV 420 planar formats,
the height should be a minimum of 16 scanlines as per BSpec
Minimum of 8 scanlines is for non-YUV 420 planar formats.
Patch changes the minimum fb height being used in the test
in case of YUV 420 planar (for now NV12 as only that is supported).
