drivers/perf: hisi_pcie: Rename hisi_pcie_pmu_{config,clear}_filter()

hisi_pcie_pmu_{config,clear}_filter() are config/clear HISI_PCIE_EVENT_CTRL
register which contains not only the filter but also the event code. The
function names are bit misleading. Rename it to
hisi_pcie_pmu_{config,clear}_event_ctrl() to reflects their functions
more accurately.
