From: Thomas Abraham <thomas...@samsung.com>
The existing Exynos 32-bit platform support needs to be realigned in
order to support newer 64-bit Exynos platforms. The driver model will
be utlized for drivers on the 64-bit Exynos platforms and so some of
the older platform support code would not be required for the newer
64-bit Exynos platforms.
