Daniel Vetter 72fdb40c1a drm: extract drm_atomic_uapi.c 
This leaves all the commit/check and state handling in drm_atomic.c,
while pulling all the uapi glue and the huge ioctl itself into a
seprate file.

This seems to almost perfectly split the rather big drm_atomic.c file
into 2 equal sizes.

Also adjust the kerneldoc and type a very terse overview text.

v2: Rebase.

v3: Fix tiny typo.

v4:
- Fixup armada, newly converted atomic driver hooray!
- Fixup msm/dpu1, newly added too.
