We make the initial value of event ctrl register as HISI_PCIE_INIT_SET
and modify according to the user options. This will make TLP headers
bandwidth only counting never take effect since HISI_PCIE_INIT_SET
configures to count the TLP payloads bandwidth. Fix this by making
the initial value of event ctrl register as 0.
