[PATCH] drm/rockchip: 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.

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

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:
A multitude of similar patches have been merged for other drivers, search
the git log for "module autoload for OF platform driver".
