This needs a massive cleanup, but to catch bugs from the interface changes
vs the engine code cleanup, this will be done later.

There's lots of more-or-less independant engines present on NVIDIA GPUs
these days, and we generally want to perform the same operations on them.
Implementing new ones requires hooking into lots of different places,
the aim of this work is to make this simpler and cleaner.
NV84:NV98 PCRYPT moved over as a test.

This commit changed an internal radeon structure, that meant a new driver
in -next had to be fixed up, merge in the commit and fix up the driver.
Also fixes a trivial nouveau merge.

The per-vm mutex doesn't prevent this completely, a flush coming from the
BAR VM could potentially happen at the same time as one for the channel
VM. Not to mention that if/when we get per-client/channel VM, this will
happen far more frequently.

The immediate benefit of doing this is that on NV50 and up, the GPU
virtual address of any buffer is now constant, regardless of what
memtype they're placed in.

As of this commit, it's guaranteed that if an object is in VRAM that its
GPU virtual address will be constant.
