PCI: Mark NVIDIA T4 GPUs to avoid bus reset

[ Upstream commit d5af729dc2071273f14cbb94abbc60608142fd83 ]

NVIDIA T4 GPUs do not work with SBR. This problem is found when the T4 card
is direct attached to a Root Port only. Avoid bus reset by marking T4 GPUs
PCI_DEV_FLAGS_NO_BUS_RESET.

Fixes: 4c207e7121fa ("PCI: Mark some NVIDIA GPUs to avoid bus reset")
