Add PCIe hardware statistics support to the fbnic driver. These stats
provide insight into PCIe transaction performance and error conditions.
Which includes, read/write and completion TLP counts and DWORD counts and
debug counters for tag, completion credit and NP credit exhaustion
The stats are exposed via debugfs and can be used to monitor PCIe
performance and debug PCIe issues.

This adds support to show firmware version information for both stored and
running firmware versions. The version and commit is displayed separately
to aid monitoring tools which only care about the version.
Example output:
