f6e7393ede drm/nouveau: Use fallthrough pseudo-keyword
Replace the existing /* fall through */ comments and its variants with
the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary
fall-through markings when it is the case.

d83d345338 drm/nouveau/bios/dp: make array vsoff static, shrinks object size
Don't populate the array vsoff on the stack but instead make it
static. Makes the object code smaller by 67 bytes:

Before:
   text	   data	    bss	    dec	    hex	filename
   5753	    112	      0	   5865	   16e9	.../nouveau/nvkm/subdev/bios/dp.o

After:
   text	   data	    bss	    dec	    hex	filename
   5622	    176	      0	   5798	   16a6	.../nouveau/nvkm/subdev/bios/dp.o

(gcc version 8.2.0 x86_64)

34508f9d26 drm/nouveau/kms/nv50-: determine MST support from DP Info Table
GV100 doesn't support MST, use the information provided in VBIOS tables to
detect its presence instead.

We only need to mask 0x0f on GM2xx, and want to keep the higher bits on
earlier cards.

d390b48027 drm/nouveau/bios: 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.
