Both "aspeed_intc_read" and "aspeed_intc_write" callback functions were used for INTC (CPU Die). To support the INTCIO (IO Die) model, introduces a new "reg_ops" class attribute. This allows setting different memory region operations to support different INTC models. Will introduce "aspeed_intcio_read" and "aspeed_intcio_write" callback functions are used for INTCIO.
