from bouyer:
- Add some debug printf (WDCPROBE) in _wdcreset_wait(), I've needed these
2 times in the past
- Set up timeout per xfer instead of per interrupt. This helps with
PIO transfer (we would call timeout()/untimout() several times for a
transfer).
- If we missed an interrupt for a PIO transfer, reset and restart it
immedialy, don't try to recover and continue. If we missed an interrupt we
may have lost a read/write cycle on the IDE bus. If this happens 1) we
corrupt data and 2) we enter an interrupt loop at the end of the xfer, as
the drive has some more data to read/write, but the host thinks the xfer is
done.
This last change fix the (or at last some of the) 'lookup after lost interrupt'
some peoples have been experiencing.

printed line with the name of hard disk.

Separate wdc_probe_caps into wdc_probe_caps and wdc_print_caps for more
flexibility in printing capability information.
Get rid of wdc_final_attach.
Include name of device (e.g. cd0), if possible, on errors.
atapiscsi layer work:
Put a pointer to the SCSI device into ata_drive_datas' drv_softc field
Simplify, simplify, simplify. Got rid of a bunch of fields in atapiscsi_softc
Delay printing capabilities until we know the real device name (e.g. st0)

Should really use viscopy() when copying atap_model -> d_packname.
When wd's become sd's this will be trivial (viscopy() lives in sd.c)

use b* instead of mem* functions, adhere to NISADMA for DMA support.
