[Nouveau] [PATCH 2/3] drm/nouveau/disp: quirk for SOR crossbar routing
With DCB 4.1 implemented by VBIOS since GM20x GPUs, SOR crossbar
routing should be possible, such that any SOR sublink can drive
any macro link.
Unfortunately, there's at least one card where some SOR sublinks
being connected to a particular macro link are causing failures.
To work around this issue, supply a quirk for such cards which
prevents a dynamic mapping of SOR sublink and macro link and
instead relies on identity mapping.

[Nouveau] [PATCH 3/3] drm/nouveau/pci: SOR crossbar quirk for 10b0:1b81
On Gainward GTX 1070 routing any other SOR than SOR-1 to macro link
'G' (outp index 7) causes failures:
[ 6.712111] nouveau 0000:01:00.0: bus: MMIO read of 00000000 FAULT at 61c880
[ IBUS ]
[ 6.724888] nouveau 0000:01:00.0: disp: intr24 80000000
[ 8.716668] nouveau 0000:01:00.0: DRM: base-0: timeout
[ 10.716679] nouveau 0000:01:00.0: DRM: base-1: timeout
[ 63.511862] nouveau 0000:01:00.0: DRM: EVO timeout
As I'm not able to spot an issue in the driver, I suppose it's
firmware related.
Therefore to work around this issue skip crossbar routing for this
particular macro link and instead use identity mapping.

I'd like to look into this some more and be 100% certain this is indeed a quirk, and not some subtle driver bug.
