[ARM] colibri: fix support for DM9000 ethernet device

Two changes are necessary to enable proper operation of the DM9000 device with
the Colibri PXA 270 board: firstly, the IRQ type needs to be configured for
rising edge interrupts, and secondly this configuration needs to be
communicated through to the DM9000.
