drm/fourcc: Pass the format_info pointer to drm_format_plane_width/height
So far, the drm_format_plane_height/width functions were operating on the
format's fourcc and was doing a lookup to retrieve the drm_format_info
structure and return the cpp.
However, this is inefficient since in most cases, we will have the
drm_format_info pointer already available so we shouldn't have to perform a
new lookup. Some drm_fourcc functions also already operate on the
drm_format_info pointer for that reason, so the API is quite inconsistent
there.
Let's follow the latter pattern and remove the extra lookup while being a
bit more consistent.
In order to be extra consistent, also rename that function to
drm_format_info_plane_cpp and to a static function in the header to match
the current policy. The parameters order have also be changed to match the
other functions prototype.
