drm/sun4i: frontend: Add support for tiled YUV input mode configuration
This introduces the data input mode definitions for the tiled YUV mode, that are used in the input mode helper if tiling is requested. The modifier is passed to the helper from the framebuffer to determine if tiling is requested. Only semiplanar and planar YUV formats are supported for tiling mode.
