If user has emit'd reloc's, and then resets or deletes the ring, we want

The normal bo cache uses some intermediate steps between power of two
jumps to reduce memory wastage. But for a ringbuffer bo cache, we do
not need this.

With a new enough drm/msm, we can let the kernel know about buffers that
are in the bo cache, so the kernel can free them under memory pressure.

Split out interface to allocate from and release to bo-cache, and get
rid of direct usage of bucket level API from fd_bo/etc.

Eventually we'll want a separate bo-cache for ringbuffer bo's, since
ringbuffer bo's get vmap'd on the kernel side, it is preferrable to
re-use them as ringbuffers rather than something else. Plus should
help to add madvise support if it is a bit better decoupled from bo
allocation (next patch).

Provide a way to insert a reference (ie. OUT_IB()) to a target ring,
executing all the cmds in the target ring from the start.
Sometimes the ringmarker stuff is just overkill. And it will won't
really work properly once we support multiple physical cmdstream buffers
per fd_ringbuffer. So in the future the old ringmarker related APIs
will be deprecated in a few releases.

Move the target device to the start of the list during iteration. This
way during deduplication it'll preserve its place and will be returned

This is unusual. Usually IDs listed on early stages of platform
definition are kept there as reserved for later use.
However these IDs here are not listed anymore in any of steppings
and devices IDs tables for Kabylake on configurations overview
section of BSpec.
So it is better removing them before they become used in any
other future platform.
v2: Rebase.

to add GEM bo mmap support. It was never used in-kernel in merged code
nor in userspace. Nuke it to align with kernel headers.

drm/bufs: remove handling of _DRM_GEM mappings
Gone with the new gem vma offset manager from David.
We can also ditch the uapi header definition from the enum since
userspace never used this. It ended up in there purely for historical
reasons (for reusing the old drm mmap code essentially), not because
userspace ever needed it.
