Subject: Revert "drm/exynos: remove MODULE_DEVICE_TABLE definitions"

This reverts commit d0896218 was
original to prevent multiple MODULE_DEVICE_TABLE in one module.
Which, as a side-effect broke autoloading of the module.

Since 21bdd17b it is possible to have
multiple calls to MODULE_DEVICE_TABLE, so the patch can be
reverted to restore support for autoloading
