HiSilicon PCIe PMU support count the bandwidth of TLP headers, TLP payloads
or both. Add support for it. User can set this through perf tool's
'len_mode' like:

  $# perf stat -e hisi_pcie0_core0/rx_mrd_flux,len_mode=0x1/ sleep 5

Also includes fixes and improvement of both driver and documentation in this
series.

Change since v2:
