Bind the hwmon structs to nouveau device kobj. This makes sure
the hwmon files are created in the device subdir in line with
all other hwmon drivers.

Current 3D driver expects this behaviour.  While this could be changed,
there's no compelling reason to reserve more than one subchannel for the
DRM.  If we ever need to use an object other then M2MF, we can just
re-bind subchannel 0 as required.

When hacking the libdrm for improvements, I triggered a kernel crash
related to the fact that the NOUVEAU_NOTIFIEROBJ_ALLOC ioctl calls
nouveau_channel_get with an unchecked channel index.
The patch ensures that the channel index is an unsigned and validates
its value in nouveau_channel_get.

CONFIG_ACPI_VIDEO depends on more than just CONFIG_ACPI, so add those
dependencies to the Kconfig select condition.  The case where some
dependencies fail to be satisfied should be handled correctly, because
in that case the ACPI_VIDEO symbols we use are converted into
static-inline stubs.

* 'nouveau/drm-nouveau-next' of ../drm-nouveau-next: (93 commits)
  drm/nv50: fix a couple of vm init issues
  drm/nv04-nv40: Fix up PCI(E) GART DMA object bus address calculation.
  drm/nouveau: kick vram functions out into an "engine"
  drm/nouveau: allow gpuobj vinst to be a virtual address when necessary
  drm/nv50: tidy up PCIEGART implementation
  drm/nv50: enable non-contig vram allocations where requested
  drm/nv50: enable 4KiB pages for small vram allocations
  drm/nv50: implement global channel address space on new VM code
  drm/nv50: implement BAR1/BAR3 management on top of new VM code
  drm/nv50: import new vm code
  drm/nv50: implement custom vram mm
  drm/nouveau: Avoid potential race between nouveau_fence_update() and context takedown.
  drm/nouveau: fix use of drm_mm_node in semaphore object
  drm/nouveau: wrap calls to ttm_bo_validate()
  drm/nouveau: no need to zero dma objects, we fill them completely anyway
  drm/nouveau: introduce a util function to wait on reg != val
  drm/nouveau: implicitly insert non-DMA objects into RAMHT
  drm/nouveau: make fifo.create_context() responsible for mapping control regs
  drm/nouveau: Spin for a bit in nouveau_fence_wait() before yielding the CPU.
  drm/nouveau: Use WC memory on the AGP GART.
  ...

Drivers using their own implementation of io_mem_reserve/io_mem_free are
likely to store the tracking information for the map in mem.mm_node, so
it can't be freed while still mapped.

this adds a bo create, and fence seq tracking tracepoints.

This is just an initial set to play around with, we should investigate
what others we need would be useful.

NVC0 will be able to share some of nv50's paths this way.  This also makes
it the card-specific vram code responsible for deciding if a given set
of tile_flags is valid, rather than duplicating the allowed types in
nv50_vram.c and nouveau_gem.c
