Introduce wdc_output_bytes and wdc_input_bytes to remove replicated PIO logic
Fix wdc_select_drive to no longer wait for free channel (not strictly correct but we couldn't handle a non-free channel anyway) Major changes to the ATAPI interrupt logic to reduce reliance on the drive setting the bits correctly. Deal with situation that we get length = 0 back from the drive on transfer (instead of potentially looping forever). Timeout in drive setup should not cause the drive to downgrade modes.
