b9a995def6 drm/nouveau/mc: add GP10B support

a558be625c drm/nouveau/msgqueue: support for GP10B PMU firmware
The GP10B firmware is very close to GM20B's. The only difference is that
it supports booting multiple falcons. In order to avoid having too much
functions and structures shared, implement its support in the same
source file as GM20B firmware.

Allow the MC base address to be specified as an argument for the WPR
region reading function. GP10B uses a different address layout as GM20B,

2963a06a4d drm/nouveau/secboot: pass instance to LS firmware loaders
Having access to the secboot instance loading a LS firmware can be
useful to LS firmware handlers. At least more useful than just having an
out-of-context subdev pointer.

GP10B's firmware will also need to know the WPR address, which can be
obtained from the secboot instance.

598a8148e7 drm/nouveau/secboot: allow to boot multiple falcons
Change the secboot and msgqueue interfaces to take a mask of falcons to
reset instead of a single falcon. The GP10B firmware interface requires
FECS and GPCCS to be booted in a single firmware command.

For firmwares that only support single falcon boot, it is trivial to
loop over the mask and boot each falcons individually.

e5ffa727e5 drm/nouveau/imem/gk20a: Turn instmem lock into mutex
The gk20a implementation of instance memory uses vmap()/vunmap() to map
memory regions into the kernel's virtual address space. These functions
may sleep, so protecting them by a spin lock is not safe. This triggers
a warning if the DEBUG_ATOMIC_SLEEP Kconfig option is enabled. Fix this
by using a mutex instead.

ac799acaa4 drm/nouveau/mmu/nv4a: use nv04 mmu rather than the nv44 one
The NV4A (aka NV44A) is an oddity in the family. It only comes in AGP
and PCI varieties, rather than a core PCIE chip with a bridge for
AGP/PCI as necessary. As a result, it appears that the MMU is also
non-functional. For AGP cards, the vast majority of the NV4A lineup,
this worked out since we force AGP cards to use the nv04 mmu. However
for PCI variants, this did not work.

Switching to the NV04 MMU makes it work like a charm. Thanks to mwk for
the suggestion. This should be a no-op for NV4A AGP boards, as they were
using it already.
