Subject: [PATCH v3 04/21] drm/sun4i: frontend: Pass DRM format info to input mode helper

The helper returning the input mode needs to know the number of planes
for the provided format. Passing the fourcc requires iterating through
the format info list in order to return the number of planes.

Pass the DRM format info structure directly instead, since it's
available to the caller. Also rename the input format in the caller
function to keep things consistent.
