* Update Intel IXP4xx support

- Add IXP4xx NPE ethernet MAC support
- Add support for Intel IXDPG425 board
- Add support for Prodrive PDNB3 board
- Add IRQ support
Patch by Stefan Roese, 23 May 2006

[This patch does not include cpu/ixp/npe/IxNpeMicrocode.c which still
 sufferes from licensing issues. Blame Intel.]
