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.

dma-buf: specify usage while adding fences to dma_resv obj v72022-04-07T10:53:53+00:00Christian Königchristian.koenig@amd.com2021-11-09T10:08:18+00:00urn:sha1:73511edf8b196e6f1ccda0fdf294ff57aa2dc9db
Instead of distingting between shared and exclusive fences specify
the fence usage while adding fences.
Rework all drivers to use this interface instead and deprecate the old one.
v2: some kerneldoc comments suggested by Daniel
v3: fix a missing case in radeon
v4: rebase on nouveau changes, fix lockdep and temporary disable warning
v5: more documentation updates
v6: separate internal dma_resv changes from this patch, avoids to
disable warning temporary, rebase on upstream changes
v7: fix missed case in lima driver, minimize changes to i915_gem_busy_ioctl

Audit all the users of dma_resv_add_excl_fence() and make sure they
reserve a shared slot also when only trying to add an exclusive fence.
This is the next step towards handling the exclusive fence like a
shared one.
v2: fix missed case in amdgpu
v3: and two more radeon, rename function
v4: add one more case to TTM, fix i915 after rebase

As the name says global memory and bo accounting is global. So it doesn't
make to much sense having pointers to global structures all around the code.

This allows blocking for BOs to become available

Amdgpu is doing this for quite a while now during CS. Now
apply the new behavior to all drivers using TTM.
