The initial implementation of non-DMA transfers was based upon analysis of traces from the MacOS toolbox ROM for handling unaligned reads but missed one key aspect - during a non-DMA transfer from the target, the bus service interrupt should be raised for every single byte received from the bus and not just at either the end of the transfer or when the FIFO is full. Adjust the non-DMA code accordingly so that esp_do_nodma() is called for every byte received from the target. This also includes special handling for managing the change from DATA IN to STATUS phase as this needs to occur when the final byte is read out from the FIFO, and not at the end of the transfer of the last byte into the FIFO.
