Move contents of edprobe() into ed_find() -- they'll be used by edattach() 

eventually.  rename the probe functions for the various boards to 'find' for
consistency/correctness (but the generic8390 check is still a 'probe').
Add protos for ed_find(), ed_probe_generic8390(), ed_find_WD80x3(),
ed_find_3Com(), and ed_find_Novell().  Fix one minor space nit.
