Add support for the AXUS TC320 thin client.

This board uses nearly the same devices as the BCOM Winnet100, so most of
the new code here is from the BCOM Winnet100. They differ in the IRQ routing
table only.

BTW: The AXUS board uses standard DIMM memory and can be run at 100MHz SDRAM
clock speed (it runs reliably here since month).
