Russell King 07555c9880 OMAP: enable smc911x support for LDP platform
The following patch enables SMC911x support to work on the OMAP LDP
board.  Although the SMC911x driver will eventually be obsoleted, the
smsc911x patches are rather invasive for the -rc kernels.

Rather than risk destablising smsc911x, this simpler patch is preferred
to allow the network interface to work.
