drm/nouveau/acr: use common falcon HS FW code for ACR FWs

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.

- gv100 split from gp108 to handle FW exit status differences

drm/nouveau/sec2: unload RTOS before tearing down WPR

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.

v2:
- fixed some excessive indentation

drm/nouveau/nvfw: firmware structures should begin with nvfw_

Rename all structures that are used directly by firmware to have a nvfw_
prefix.

This makes it easier to identify structures that have a fixed, specific
layout. A future patch will define several more such structures, so it's
important to be consistent now.

drm/nouveau/flcn/msgq: move handling of init message to subdevs

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.

drm/nouveau/flcn/qmgr: support syncronous command submission from common code

Functions implementing FW commands had to implement this themselves, let's
move that to common code and plumb the return code from callbacks through.

drm/nouveau/flcn/qmgr: allow arbtrary priv + return code for callbacks

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.

There should be no code changes here, these will be done incrementally.
