Shortcut to avoid each subdev having to do this itself.
Signed-off-by: NBen Skeggs <bskeggs@redhat.com>

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.

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.

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.

Writing the 0x1704 (BUS_BAR1_BLOCK) register causes the GPU to probe the
memory region at the programmed address. The result is an address decode
error in the external memory controller because address 0, which is what
is written to the register, is not designated as accessible to devices.

Avoid triggering DMA from the GPU by removing teardown of the BAR1.

Some, mostly Fermi, vbioses appear to have zero max voltage. That causes Nouveau to not parse voltage entries, thus users not being able to set higher clocks.

When changing this value Nvidia driver still appeared to ignore it, and I wasn't able to find out why, thus the code is ignoring the value if it is zero.

There's already a condition in place which attempts to detect this, but
since we've begun to require a PMU subdev even on boards where we don't
load a custom FW, it's become inaccurate.

GP100 and newer, where we don't yet override the default PMU FW.
