Break vsp1_du_setup_lif() into components more suited to the DRM Atomic
API. The existing vsp1_du_setup_lif() API call is maintained as it is
still used from the DU.

Shouldn't this paragraph be preserved, as the function keeps its
pipe_index argument ?

Not a big fan of this description or of the vsp1_du_enable_config name,
but I can't really think of a better alternative. vsp1_du_callback would
be an option, but it would prevent us from adding new fields not related
to the callback.

I think you can now drop this comment, or at least the first part of the
sentence.

This now holds on a single line.

And this can hold on two lines.
