[PATCH RFC 7/7] ARM: dts: omap3-igep0020: Add SMSC911x LAN chip support

[Javier Martinez Canillas <javier.martinez@collabora.co.uk>]

IGEPv2 boards has an SMSC LAN9221i ethernet chip connected to
the OMAP3 processor though the General-Purpose Memory Controller.

This patch adds a device node for the ethernet chip so the GPMC
driver will call the gpmc-smsc911x setup code.
