As we are going to add virtual planes, add the list of supported formats
to the hw catalog entry. It will be used to setup universal planes, with
later selecting a pipe depending on whether the YUV format is used for
the framebuffer.




If your usage of format_list is going to be internal to dpu_plane.c, I 
can think of another idea for this change.


This essentially translates to if (num_vig >= 1)


If we can just have a small helper to detect that from the catalog can 
we use that instead of adding formats to the dpu caps?
