eth: fbnic: add coverage for RXB stats
This patch provides coverage to the RXB (RX Buffer) stats. RXB stats
are divided into 3 sections: RXB enqueue, RXB FIFO, and RXB dequeue
stats.
The RXB enqueue/dequeue stats are indexed from 0-3 and cater for the
input/output counters whereas, the RXB fifo stats are indexed from 0-7.
The RXB also supports pause frame stats counters which we are leaving
for a later patch.
