We need these offsets for PCIE perf counters, so include them as well as
the the previously-used defines from the nbio_*.c files
v2: Return NBIF definitions back to previous files

Add a sysfs file that reports the number of bytes transmitted and
received in the last second. This can be used to approximate the PCIe
bandwidth usage over the last second.
v2: Clarify use of mps as estimation of bandwidth
