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/flcn: show falcon user in debug output

Displays both owner/user of the falcon (when they differ), and takes
both subdevs' debug levels into account when deciding whether to log
the message.

- runlist debugging will use one of the alternate macros added here

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/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.

drm/nouveau/flcn: split msgqueue into multiple pieces

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.
