Until now the parameter of the ADDR_TIMING_MODE feature was just the ONFI timing mode (from 0 to 5) because we were only supporting the SDR data interface. In the same byte, bits 4 and 5 indicate which data interface is being configured so use them to set the right mode and also read them back to ensure the right timing has been setup on the chip's side.
