[PATCH 1/3] drm/exynos: revert fixes for the infinite loop issue

[Gustavo Padovan]

From: Gustavo Padovan <gustavo.padovan at collabora.co.uk>

This reverts commit 06a2f5c2c4e0cb4ff38ca3769ae1f81cc2d030cf and
f7c2f36f4395f12d8ecb25c28ee88ec87b457089.

These two patches were trying to fix an issue that was causing an
infinite loop at the load of the exynos-drm but they were not tackling the
source of the problem.

A new patch that move the platform driver registration exynos_drm_init()
follows this revert and fix the issue properly.
