 exynos-mem: Fix major security hole

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.
