Subject: [PATCH v2] PM / AVS: rockchip-io: 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.

Hello,

Sending a second version to add Rafael Wysocki in the to-list as
suggested by Heiko Stübner.
https://lkml.org/lkml/2015/10/2/431

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
