Subject: [PATCH] Colibri: Fix support for DM9000 ethernet device.

From: Michael Abbott <michael.abbott@...mond.ac.uk>

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.

Patch applied against v2.6.25

Proper operation of this device also depends on the DM9000 timer patch 
submitted separately.
