 Or not use an extra flag at all and change wdc_datain/out_pio()
 to look like the via_data{in,out}_pio versions. Most of the time
 len is a multiple of 4 anyway and if it isn't, it should be so
 small (I've seen 34 bytes with a mount_cd9660 and 74 bytes
 with the scsictl identify)  to not make much of a performance
 difference because 32-bit transfers aren't used in those case.
