Adds context binding and support for FWs with a bootloader to the code
that was added to load VPR scrubber HS binaries, and ports ACR over to
using all of it.

Mostly preparation to fit in Ampere changes, but should result in reset
sequences a lot closer to RM's, and perhaps help out with the issues we
sometimes see reported in this area.

Reset regs won't be available on Ampere while SEC2 RTOS is running, and
we're apparently supposed to be doing this on earlier GPUs too.

ASB was failing to load on Turing GPUs when firmware is being loaded
from initramfs, leaving the GPU in an odd state and causing suspend/
resume to fail.
Add missing MODULE_FIRMWARE() lines for initramfs generators.

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 us to register the falcon with ACR, and further customise
its behaviour by providing the nvkm_falcon_func structure directly.
