Log Message:
add ata_channel lock, use it to protect queue manipulation (only that for now);
add ata_channel_detach() to destroy the locks

change ata_get_xfer() so that it can wait for xfer, convert all on-stack
xfer code to use the blocking variant

fix siisata_reset_drive() to use polled reset and not try ata_activate_xfer(),
convert drive probe code also over from slot0 XXX to ata_get_xfer()

drive reset and PMP now works on siisata(4) too; changes tested also
on piixide(4), ahci(4), mvsata(4)
