Fixes hitting WARN_ON() during initialisation of pre-NV50 GPUs, caused
by the recent changes to support pad macro routing on GM20x.
We currently don't use them here for older GPUs anyway.

Bit 30 being set causes the upper half of BAR2 to stay in physical mode,
mapped over the end of VRAM, even when the rest of the BAR has been set
to virtual mode.
We inherited our initial value from RM, but I'm not aware of any reason
we need to keep it that way.
This fixes severe GPU hang/lockup issues revealed by Wayland on F26.
Shout-out to NVIDIA for the quick response with the potential cause!

These on()/off() calls should be done as a result of modesetting actions,
and as we shut down all heads already on unload/suspend, it's pointless
to call off() again.

We don't support them on G80, but we need to add them to the mapping to
avoid triggering a WARN_ON() on GPUs where the ports are present.

Since switching the I2C-over-AUX helpers, there have been regressions on
some display combinations due to us not having support for "address only"
transactions.
This commits enables support for them for GF119 and newer.
Earlier GPUs have been reverted to a custom I2C-over-AUX algorithm.

Pull uuid subsystem from Christoph Hellwig:
"This is the new uuid subsystem, in which Amir, Andy and I have started
consolidating our uuid/guid helpers and improving the types used for
them. Note that various other subsystems have pulled in this tree, so
I'd like it to go in early.
UUID/GUID summary:
- introduce the new uuid_t/guid_t types that are going to replace the
somewhat confusing uuid_be/uuid_le types and make the terminology
fit the various specs, as well as the userspace libuuid library.
(me, based on a previous version from Amir)
- consolidated generic uuid/guid helper functions lifted from XFS and
libnvdimm (Amir and me)
- conversions to the new types and helpers (Amir, Andy and me)"

There is a prototype for this function in the header, but the function
itself lacks a 'void' in the argument list, causing a harmless warning
when building with 'make W=1':

As with vga_init, this function doesn't make sense on non-PCI devices,
and the Thunderbolt check in it dereferences a NULL pointer in that
case. Add some code to skip this function when the device is not a PCI
device.

We check if we have support for them, and if we do, we gather them all in

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.
