drm/sun4i: frontend: Add and use helper for checking tiling support

This introduces a helper to check whether a frontend input format
supports tiling mode. This helper is used when tiling is requested in
the frontend format support helper.

Only semiplanar and planar YUV formats are supported by the hardware.
