drivers/perf: hisi: Fixup one DDRC PMU register offset

Browse Source 
For DDRC PMU, each PMU counter is fixed-purpose. There is a mismatch
between perf list and driver definition on rw_chg event.
# perf list | grep chg
  hisi_sccl1_ddrc0/rnk_chg/                          [Kernel PMU event]
  hisi_sccl1_ddrc0/rw_chg/                           [Kernel PMU event]
But the register offset of rw_chg event is not defined in the driver,
meanwhile bnk_chg register offset is mis-defined, let's fixup it.
