[PATCH RFC 5/7] ARM: OMAP: gpmc: add support for gpmc-smsc911x child nodes

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

Besides being used to interface with external memory devices,
the General-Purpose Memory Controller can be used to connect
Pseudo-SRAM devices to the OMAP processor that use the GPMC
as a data bus. One of these devices is the smsc911x LAN chip.

This patch allows an smsc911x LAN pheripheral to be defined
as an GPMC child node an call its corresponding setup function.
