PCI: Add no PM reset quirk for NVIDIA Spectrum devices
Spectrum-{1,2,3,4} devices report that a D3hot->D0 transition causes a
reset (i.e., they advertise NoSoftRst-). However, this transition does
not have any effect on the device: It continues to be operational and
network ports remain up. Advertising this support makes it seem as if a
PM reset is viable for these devices. Mark it as unavailable to skip it
when testing reset methods.
Before:
# cat /sys/bus/pci/devices/0000\:03\:00.0/reset_method
pm bus
After:
# cat /sys/bus/pci/devices/0000\:03\:00.0/reset_method
bus
