[PATCH v4 05/11] media: uapi: h264: Get rid of the p0/b0/b1 ref-lists

[Ezequiel Garcia]

From: Boris Brezillon <boris.brezillon@xxxxxxxxxxxxx>

Those lists can be extracted from the dpb, let's simplify userspace
life and build that list kernel-side (generic helpers will be provided
for drivers that need this list).
