New device numbers for the SCSI Scanners and new MAKEDEV

[Bernd Ernesti <netbsd%arresum.inka.de@localhost>]

Hi,

I changed the device number of the ss0 device from 25 to 37 and added uk*
and ch* devices. I also removed the expr calls in MAKEDEV and added some
minor devices nodes for some support devices (e.g. nss0 and enss0).
Hmm we need a manpage for ss to get more informations about this.

You need to rerun the new MAKEDEV to update your device files or you
get problems if you want to use a scanner or ch and uk devices.

Oh, and i finnaly added the device names for the msc* devices (A2232): ttyC*
