Split SMC chipset ARCnet driver into
- machine independent chip driver, in dev/ic/smc90cx6.c/...reg.h,...var.h, using bus_space methods - ZBUS frontend in arch/amiga/dev/if_bah_zbus.c - added IPL_SOFTNET to arch/amiga/include/intr.h, for this Implementing the ISA bus frontend is left as an exercise to the reader.
