With memory encryption active, the hypervisor typically can't read the
guest memory using the HB port, since it is encrypted using a key known
only to the guest. In that case fall back to processing 4 bytes at a time
using the ordinary backdoor port.
The other option would be to use unencrypted bounce buffers for the
hypervisor to read out from or write into, but given the limited message
sizes it appears more efficient to just fall back to the ordinary backdoor
port.

ACR is responsible for managing the firmware for LS (Low Secure) falcons,
this was previously handled in the driver by SECBOOT.
This rewrite started from some test code that attempted to replicate the
procedure RM uses in order to debug early Turing ACR firmwares that were
provided by NVIDIA for development.
Compared with SECBOOT, the code is structured into more individual steps,
with the aim of making the process easier to follow/debug, whilst making
it possible to support newer firmware versions that may have a different
binary format or API interface.
The HS (High Secure) binary(s) are now booted earlier in device init, to
match the behaviour of RM, whereas SECBOOT would delay this until we try
to boot the first LS falcon.
There's also additional debugging features available, with the intention
of making it easier to solve issues during FW/HW bring-up in the future.

We perform memory allocations long before we hit the code in SECBOOT that
would unlock the VPR, which could potentially result in memory allocation
within the locked region.
Run the scrubber binary right after VRAM init to ensure we don't.

When the PMU/SEC2 LS FWs have booted, they'll send a message to the host
with various information, including the configuration of message/command
queues that are available.
Move the handling for this to the relevant subdevs.

This moves the code to generate commands for the ACR unit of the PMU/SEC2 LS
firmwares to those subdevs.

Takes the command queue pointer directly instead of requiring a function to
lookup based on an queue type, as well as an explicit timeout value.

Functions implementing FW commands had to implement this themselves, let's
move that to common code and plumb the return code from callbacks through.
Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
Code to interface with LS firmwares is being moved to the subdevs where it
belongs, rather than living in the common falcon code.
Arbitrary private data passed to callbacks is to allow for something other
than struct nvkm_msgqueue to be passed into the callback (like the pointer
to the subdev itself, for example), and the return code will be used where
we'd like to detect failure from synchronous messages.

To make things clearer while modifying the interfaces, split msgqueue into
Queue Manager, Command Queue, and Message Queue.
There should be no code changes here, these will be done incrementally.

This will allow us to register the falcon with ACR, and further customise
