Seen on Titan. NFI what the condition to switch this on is yet, and,
hardcoding it to on currently causes master to report unknown intr
with a mask of 0x08002000.

Still essentially a struct of magic values with magic names and unknown
purposes. But, we will shortly need to be able to mix and match bits of
the previous and next configurations to do a transition reclock, as such,
we can no longer directly use the vbios data with any ease.
This is probably nicer anyway in the long run, for a few reasons.

Compute code in mesa triggers one of these, hanging the engine. Let's
at least ack the request for now to avoid the hang.

Some firmware images may be large (64K), so using kmalloc memory is
inappropriate for them. Use vmalloc instead, to avoid high-order
allocation failures.

Now that nouveau_bo.c can handle sync when it actually needs to, we can
remove this and avoid a double semaphore acquire when syncing in the
command submission path.

Moves bo's to TTM_PL_TT for BAR mapping, to hide tiling from user.

Commit de7b7d59d54852c introduced tiled GART, but a linear copy is
still performed. This may result in errors on eviction, fix it by
checking tiling from memtype.

Pretty much everywhere had to make the decision which to use, so it
makes a lot more sense to just have one entrypoint decide the path
to take instead.

When the mode is set with 16bpp on QEMU, the output gets totally broken.
The culprit is the bogus register values set for 16bpp, which was likely
copied from from a wrong place.
