From: "Dr. David Alan Gilbert" <linux@treblig.org>
dcb_outp_match() last use was removed in 2017 in
commit 99a845a30f62 ("drm/nouveau/disp/nv50-gt21x: remove workaround for
dp->tmds hotplug issues")
dcb_xpio_parse was added in 2012 in
commit 112a12aab8a5 ("drm/nouveau/bios: add support for parsing xpio table
data")
but never used.
Remove them.
dcb_xpio_parse was the last user of struct nvbios_xpio, so remove it
as well and the FLAG #defines.

Thanks for the ping! The patch looks fine to me but I'm not sure if we would
want to remove something like this, or just comment it out with #if 0. Ben, do
you have any particular feelings on this?
