hw/intc/loongarch_pch: Use unified trace event for memory region ops

Add trace event trace_loongarch_pch_pic_read(), replaces the following
three events:
  trace_loongarch_pch_pic_low_readw()
  trace_loongarch_pch_pic_high_readw()
  trace_loongarch_pch_pic_readb()
The similiar with write trace event.
