Shortcut to avoid each subdev having to do this itself.

We want to be able to register falcons with ACR during the constructor for
the subdev it belongs to, however, we may not have access to the falcon's
registers prior to DEVINIT.
Delay touching registers until the first time the falcon is acquired.
This may temporarily break secboot on non-production boards due to not
being able to determine whether the falcon is in debug or production mode,
the new ACR subdev will not have this issue, and it's not a use-case that's
terribly important for bisectability.

Method init is typically ordered by class in the FW image as ThreeD,
TwoD, Compute.
Due to a bug in parsing the FW into our internal format, we've been
accidentally sending Twod + Compute methods to the ThreeD class, as
well as Compute methods to the TwoD class - oops.

We accidentally set "psb" which is a no-op instead of "*psb" so it
generates a static checker warning. We should probably set it before
the first error return so that it's always initialized.

Turing introduced a new simplified page kind
scheme, reducing the number of possible page
kinds from 256 to 16. It also is the first
NVIDIA GPU in which the highest possible page
kind value is not reserved as an "invalid" page
kind.
To address this, the invalid page kind is made
an explicit property of the MMU HAL, and a new
table of page kinds is added to the tu102 MMU
HAL.
One hardware change not addressed here is that
0x00 is technically no longer a supported page
kind, and pitch surfaces are instead intended to
share the block-linear generic page kind 0x06.
However, because that will be a rather invasive
change to nouveau and 0x00 still works fine in
practice on Turing hardware, addressing this new
behavior is deferred.

The pointer used to walk the table of move ops
and pick the right one for the current GPU was
declared static, meaning its state was carried
over between invocations of the function, and also
made the function non-rentrant and thread-unsafe.
Since the table is ordered such that newer GPU
methods are listed first, the result of this was
that initializing newer GPUs after older GPUs
would result in no suitable ttm move acceleration
operations being found, and ttm would fall back
to CPU blits on the older GPUs.
This change declares the walking pointer
separately from the table and makes it non-static
to fix the logic.

gp10b uses the new engine enumeration mechanism introduced in the Pascal
architecture. As a result, the copy engine, which used to be at index 2
for prior Tegra GPU instantiations, has now moved to index 0. Fix up the
index and also use the gp100 variant of the copy engine class because on
gp10b the PASCAL_DMA_COPY_B class is not supported.

When the GPU powergate is controlled by a generic power domain provider,
the reset will automatically be asserted and deasserted as part of the
power-ungating procedure.
On some Jetson TX2 boards, doing an additional assert and deassert of
the GPU outside of the power-ungate procedure can cause the GPU to go
into a bad state where the memory interface can no longer access system
memory.

There is no BAR2 on GP10B and there is no need to map through BAR2
because all memory is shared between the GPU and the CPU. Add a custom

to be the same size so it worked, however, this should be fixed
