[PULL] nouveau: ampere modesetting

[Ben Skeggs]

Hey Dave,

This series of patches to add modesetting support for Ampere has been
pulled out of a larger, more invasive series.  As there's currently no
firmware available for us to use, the rest of it isn't important right
now, and it'd be nice to have something non-invasive to provide what
support we currently can (and is possible to backport to earlier
kernels).

No other chipset should be impacted by these patches, as the changes
are largely confined to adding Ampere versions of the code handling
each IP block.

I'd like to extend thanks to NVIDIA for providing hardware, and for
their assistance with confirming/clarifying some of the changes.

Ben.
