Merge and cleanup the two headers into a single description of the
object API. Also move all the documentation to the implementation and
drop unnecessary includes from the header.
No functional change.

Backmerge tag 'v6.1-rc6' into drm-next
Linux 6.1-rc6
This is needed for drm-misc-next and tegra.

It turned out that not the last IB specified is the gang leader,
but instead the last job allocated.
This is a bit unfortunate and not very intuitive for the CS
interface, so try to fix this.

Fixes: 4624459c84 ("drm/amdgpu: add gang submit frontend v6")
Allows submitting jobs as gang which needs to run on multiple engines at the
same time.
All members of the gang get the same implicit, explicit and VM dependencies. So
no gang member will start running until everything else is ready.
The last job is considered the gang leader (usually a submission to the GFX
ring) and used for signaling output dependencies.
Each job is remembered individually as user of a buffer object, so there is no
joining of work at the end.
v2: rebase and fix review comments from Andrey and Yogesh
v3: use READ instead of BOOKKEEP for now because of VM unmaps, set gang
leader only when necessary
v4: fix order of pushing jobs and adding fences found by Trigger.
v5: fix job index calculation and adding IBs to jobs
v6: fix typo found by Alex

Instead of providing the ib index provide the job and ib pointers directly to
the patch and parse functions for UVD and VCE.
Also move the set/get functions for IB values to the IB declerations.

No function change, just move a bunch of definitions from amdgpu.h into
separate header files.
