Ed Schouten 4c88ba2d70 Unobfuscate unit number handling in apm(4).
There is no need to use the lower 4 bits of the unit number to store the
device type number. Just use 0 and 1 to distinguish them. devfs also
guarantees that there can never be an open call on a device that has a
unit number different to 0 and 1, so there is no need to check for this
in open().
