Preliminary fix for exynos-mem exploit (for more details, see http://forum.xda-developers.com/showthread.php?p=35560095)

/dev/exynos-mem if chmodded 400 in init.rc and 400 is default permission in kernel as well (reverse-merged from commit d9c845ce145354e50a8300dbd9c07d7a988e4efd)
exynos-mem: Fix major security hole

- all credits to AndreiLux

- adjusted to work with Samsung Update6 source code by andip71

This fixes the exynos-mem device security hole. The driver allowed any user
to access all of the device's lowmem through the provided mmap functionality.

We create a small little framework collecting the actual CMA memory blocks
that exist on the device; they are the root cause of the existence of this device
driver. We white-list only the CMA memory spaces as parameters to the mmap
function and deny access to any other memory space requests.

We furthermore just allow access to the "s3c-fimc" memory block as this is
seemingly the only space which upon access denial actually breaks functionality.
