PCI: Mark Nvidia GB10 to avoid bus reset
[ Upstream commit c81a2ce6b6a844d1a57d2a69833a9d0f00403f00 ]
After asserting Secondary Bus Reset to downstream devices via a GB10 Root
Port, the link may not retrain correctly, e.g., the link may retrain with a
lower lane count or config accesses to downstream devices may fail.
Prevent use of Secondary Bus Reset for devices below GB10.
