Subject: [RESEND] powerpc: axonram: Fix module autoload for OF platform driver

From: Luis de Bethencourt <luis@...ethencourt.com>

This platform driver has a OF device ID table but the OF module
alias information is not created so module autoloading won't work.

Hi,

This is a Resend of a patch from 20 Oct [0]

I am adding Andrew Morton to the CC list as was recommended at the Korea Linux
Forum.

This patch adds the missing MODULE_DEVICE_TABLE() for OF to export
that information so modules have the correct aliases built-in and
autoloading works correctly.

A longer explanation by Javier Canillas can be found here:

Thanks,
Luis
