nouveau-fixes 5.2

[Ben Skeggs]

Hey Dave,

This is a bit more than I'd like to be pushing at this point in a
cycle, but it's a fairly important issue.  There's been numerous
reports of more recent GP10[2467] boards failing to load, and I've
worked with NVIDIA FW engineers and tracked this down to the FW we've
been using not properly supporting the boards in question.

I've pushed an update to linux-firmware with the new FW version, which
unfortunately contains API changes vs the older firmware.

This series teaches the ACR subsystem inside nouveau enough to be able
to deal with supporting multiple incompatible FW revisions, and adds
support to the relevant chipsets for loading the newer FW revision, if
it's available.

Thanks,
Ben.
