drm/sun4i: frontend: Add support for semi-planar YUV input formats

Ver código fonte 
Semi-planar YUV formats use two distinct planes, one for luminance and
one for chrominance. To add support for them, we need to configure the
second line stride and buffer address registers to setup the second YUV
plane.

New definitions are introduced to configure the input format register
for the YUV420 and YUV422 semi-planar formats.
