eth: fbnic: add PCIe hardware statistics
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.
