MMU will be needing this to specify kind info on BAR mappings.
We have no userspace currently using these interfaces, so break the ABI
instead of supporting both. NVIF version bump so any future use can be
guarded.

Most of these errors seem to be WFD related. Official documentation
says dcb type 8 is reserved. It's probably used for WFD. Silence
the warning in either case.
Connector type 70 is stated to be a virtual connector for WiFi
display. Since we know this, don't warn that we don't.

This makes use of all the additional routing and state added in previous
commits, making it possible to deal with GM20x macro link routing, while
also sharing code between the NV50 and GF119 implementations.

These exist to give NVKM information on the set of display paths that
the DD needs to be active at any given time.
Previously, the supervisor attempted to determine this solely from OR
state, but there's a few configurations where this information on its
own isn't enough to determine the specific display paths in question:
- ANX9805, where the PIOR protocol for both DP and TMDS is TMDS.
- On a device using DCB Switched Outputs.
- On GM20x and newer, with a crossbar between the SOR and macro links.
After this commit, the DD tells NVKM *exactly* which display path it's
attempting a modeset on.

In order to properly support the SOR -> SOR + pad macro separation
that occurred with GM20x GPUs, we need to separate OR handling out
of the output path code.
This will be used as the base to support ORs (DAC, SOR, PIOR).

The nouveau driver, in the Linux 3.7 days, used to try and set the
AVI InfoFrame based on the selected display mode. These days, it
uses a fixed set of InfoFrames. Start to correct that, by
providing a mechanism whereby InfoFrame data may be passed to the
NVKM functions that do the actual configuration.
At this point, only establish the new parameters and their parsing,
don't actually use the data anywhere yet (since it's not supplied
anywhere).

Reusing the list_head for both is a bad idea. Callback execution is done
with the lock dropped so that alarms can be rescheduled from the callback,
which means that with some unfortunate timing, lists can get corrupted.
The execution list should not require its own locking, the single function
that uses it can only be called from a single context.

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.

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.

This commit reworks the RAM detection algorithm, using RAM-per-LTC to
determine whether a board has a mixed-memory configuration instead of
using RAM-per-FBPA. I'm not certain the algorithm is perfect, but it
should handle all currently known configurations in the very least.
This should fix GTX 970 boards with 4GiB of RAM where the last 512MiB
isn't fully accessible, as well as only detecting half the VRAM on
GF108 boards.
As a nice side-effect, GP10x memory detection now reuses the majority
of the code from earlier chipsets.

These gp10x chips are supporting using (roughly) the same firmware.
Compared to previous secure chips, ACR runs on SEC2 and so does the
low-secure msgqueue.

On some secure boot instances (e.g. gp10x) the load and unload blobs do
not run on the same falcon. Support this case by introducing a new
member to the ACR structure and making related functions take the falcon
to use as an argument instead of assuming the boot falcon is to be used.
The rule is that the load blob can be run on either the SEC or PMU
falcons, but the unload blob must be always run on PMU.

On SEC, DMEM is unaccessible by the CPU when the falcon is running in LS
mode. This makes communication with the firmware using DMEM impossible.
For this purpose, a new kind of memory (EMEM) has been added. It works
similarly to DMEM, with the difference that its address space starts at
0x1000000. For this reason, it makes sense to treat it like a special
case of DMEM.

SEC2 is the name given by NVIDIA to the SEC engine post-Fermi (reasons
unknown). Even though it shares the same address range as SEC, its usage
is quite different and this justifies a new engine. Add this engine and
make TOP use it all post-TOP devices should use this implementation and
not the older SEC.
Also quickly add the short gp102 implementation which will be used for
falcon booting purposes.

A message queue firmware implements a specific protocol allowing the
host to send "commands" to a falcon, and the falcon to reply using
"messages". This patch implements the common part of this protocol and
defines the interface that the host can use.
Due to the way the firmware is developped internally at NVIDIA (where
kernel driver and firmware evolve in lockstep), firmwares taken at
different points in time can have frustratingly subtle differences that
must be taken into account. This code is architectured to make
implementing such differences as easy as possible.
