exynos5250: add RAM resource beginning at physical address 

The original code attempted to reserve a space in RAM for coreboot to
remain resident. This turns out not to be needed, and breaks things
for the kernel since the exynos5250-smdk5250 kernel device tree starts
RAM at 0x40000000.

(This patch was originally by Gabe, I'm just uploading it)
