drm/nouveau/mmu: protect each vm with its own mutex

An upcoming commit requires being able to modify the PRAMIN BAR page
tables while already holding the MMU subdev mutex.

To solve this issue, each VM has been given its own mutex.  As a nice
side-effect, this also allows separate VMs to be updated concurrently.

drm/nouveau/nvif: simplify and tidy library interfaces

A variety of tweaks to the NVIF library interfaces, mostly ripping out
things that turned out to be not so useful.

- Removed refcounting from nvif_object, callers are expected to not be
  stupid instead.
- nvif_client is directly reachable from anything derived from nvif_object,
  removing the need for heuristics to locate it
- _new() versions of interfaces, that allocate memory for the object
  they construct, have been removed.  The vast majority of callers used
  the embedded _init() interfaces.
- No longer storing constructor arguments (and the data returned from
  nvkm) inside nvif_object, it's more or less unused and just wastes
  memory.

drm/nouveau/device: simplify subdev construction

Replaces the piece-by-piece (in response to NV_DEVICE ctor args) device
contruction with a once-off all-or-nothing approach, eliminating some
tricky refcounting issues.  The partial device init capability was only
required by some tools, and has been moved to probe time instead.

Temporarily removes a workaround for some boards where we need to fiddle
with AGP registers before executing the DEVINIT scripts.  A later commit
in this series reinstates it.

These require an explicit struct nvkm_gpuobj pointer, unlike the previous
macros which take a void *, and work with any nvkm_object.

New semantics require acquiring/releasing a gpuobj before accessing them,
which will be made use of in later patches to greatly reduce the overhead
of accesses, particularly when a direct mmio mapping of the object is not
available (suspend/resume, out of ioremap() space, and on GK20A).

drm/nouveau/core: type-safe printk macros

These require an explicit pointers to nvkm_object/nvkm_subdev/nvkm_device,
depending on which macros are used.  This is unlike the previous macros
which take a void *, and work for anything derived from nvkm_object (by
way of some awful heuristics).

The output will be a bit confused until everything has been transitioned,
as the logging format used is a more standard style that previously.

In addition, usage of pr_cont(), which doesn't work correctly with the
dev_*() printk functions (and was potentially racy to begin with), will
be replaced.
