Bring some enhancements and fixes to fdc(4) from NetBSD:
- better state machine, will prevent "eject fd0" with an empty drive to
spin.
- will not attach fd children to fdc if no floppy drive is present (though
the PROM usually finds this for us).
- use biowait() in fdformat() instead of rolling our own.
- drop 5"1/4 formats table.
- cope with non 512 bytes per sector formats.
