[PATCH v3 7/9] v4l: vsp1: Adapt entities to configure into a body

[Kieran Bingham <kieran.bingham+renesas@ideasonboard.com>]

Currently the entities store their configurations into a display list.
Adapt this such that the code can be configured into a body directly,
allowing greater flexibility and control of the content.

All users of vsp1_dl_list_write() are removed in this process, thus it
too is removed.

A helper, vsp1_dl_list_get_body() is provided to access the internal body0
from the display list.

Signed-off-by: Kieran Bingham <kieran.bingham+renesas@ideasonboard.com>

---
I don't like the fact this adds vsp1_dl_list_get_body() on top of
vsp1_dl_body_get(); which are a bit too similar.

Perhaps we should remove body0, or at least call vsp1_dl_list_get_body()
vsp1_dl_list_get_body0()...
