Subject: [RESEND] drm: imx: imx-tve: Fix module autoload for OF platform driver

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 October 20th [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:
https://lkml.org/lkml/2015/7/30/519
A multitude of similar patches have been merged for other drivers, search
the git log for "module autoload for OF platform driver".

Thanks,
Luis
