drm/nouveau/fault: Add support for GP10B
...
There is no BAR2 on GP10B and there is no need to map through BAR2
because all memory is shared between the GPU and the CPU. Add a custom
implementation of the fault sub-device that uses nvkm_memory_addr()
instead of nvkm_memory_bar2() to return the address of a pinned fault
buffer.

drm/nouveau/fault/tu104: initial support
...
New registers.
Currently uncertain how exactly to mask fault buffer interrupts. This will
likely be corrected at around the same time as the new MC interrupt stuff
has been properly figured out and implemented.
For the moment, it shouldn't matter too much.
