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.

This will allow for further customisation of the subdev depending on what
firmware is available.

ACR LS FW loading is moving out of SECBOOT and into their specific subdevs,
and the available GP107/GP108 FWs have interface differences.
