This is a follow-on series to
Commit 2d1ce5ec2117 ("PCI: Check for PCIe Link downtraining")

The remaining issues was that some pcie drivers print link status directly,
sometimes resulting in duplicate system log messages with degraded links.

From my understanding, the maintainers of these drivers are fine with
removing the duplicate prints as long as the bandwidth information is
readily available. sysfs seemed to be the consensus.

Example:

	$ cat /sys/bus/pci/devices/0000:b1:00.0/available_bandwidth
	7.876 Gb/s
