f2e55b9ea9 drm/nouveau/mc/tu104: initial support
Things are a bit different here on Turing, and will require further changes
yet once I've investigated them more thoroughly.

For now though, the existing GP100 code is compatible enough with one small
hack to forward on fault buffer interrupts.

3c2a536b0c drm/nouveau/mc: expose device enable/disable separately, as well as reset
There are cases where subdevs need to perform additonal actions around
the master reset, so we want to expost the operations separately.

This commit also adds a flag to the NV_PMC_ENABLE bitfield definitions
which allow skipping the automatic reset() called from core/subdev.c.

70b01f07db drm/nouveau/mc: allow for local definition of reset bits
With the addition of PTOP-specified reset bits, it makes more sense to
move the definitions here rather than in individual subdev
implementations.

9ace404b10 drm/nouveau/device: include core/device.h automatically for subdevs/engines
Pretty much every subdev/engine is going to need access to nvkm_device
shortly to touch registers and/or output messages.

The odd placement of the includes is necessary to work around some
inter-dependencies that currently exist.  This will be fixed later.

d7e5fcd2e7 drm/nouveau/mc: namespace + nvidia gpu names (no binary change)
The namespace of NVKM is being changed to nvkm_ instead of nouveau_,
which will be used for the DRM part of the driver.  This is being
done in order to make it very clear as to what part of the driver a
given symbol belongs to, and as a minor step towards splitting the
DRM driver out to be able to stand on its own (for virt).

Because there's already a large amount of churn here anyway, this is
as good a time as any to also switch to NVIDIA's device and chipset
naming to ease collaboration with them.

A comparison of objdump disassemblies proves no code changes.

c39f472e9f drm/nouveau: remove symlinks, move core/ to nvkm/ (no code changes)
The symlinks were annoying some people, and they're not used anywhere
else in the kernel tree.  The include directory structure has been
changed so that symlinks aren't needed anymore.

NVKM has been moved from core/ to nvkm/ to make it more obvious as to
what the directory is for, and as some minor prep for when NVKM gets
split out into its own module (virt) at a later date.
