Add Allied Telesis SIC-AT boards support.
Discussed in from [FreeBSD-tech-jp 3396] to [FreeBSD-tech-jp 3407] at FreeBSD-tech-jp@jp.freebsd.org. NOTE: We must put ed_probe_SIC() function into if_ed_isa.c because this is a bus dependent code. But the ed driver code is not separated explicitly whether it is bus dependent or independent now. Refer to: http://plaza17.mbn.or.jp/~chi/myprog/FreeBSD/sicat.html Submitted by: chi@bd.mbn.or.jp (Chiharu Shibata)
