This register counts the number of AXI cycles in which a master was requesting a transfer,
and the slave had not responded. This is including cycles in which it was requesting transfers
but was not accepted by slave yet. The master enable register
HW_PERFMON_MASTER_EN are used to mask which master(s) cycles are actually
recorded here.

Re-
21.3.7 PerfMon Transfer Count Register
The transfer count register defines the total number of transfers has been completed during
the whole monitoring period.
Divide the register HW_PERFMON_LATENCY_CYCLE value over this value of this
register will give the average latency for each transfer.
