m68knommu: platform support for 8390 based ethernet used on some boards
Quite a few of Freescale's older ColdFire development boards used an NS8390 based ethernet interface. Add a platform definition for the resources used by these devices so we can use it on these boards. Signed-off-by: Greg Ungerer <gerg@uclinux.org>
