ARM: dts: samsung: exynos4412: decrease memory to account for unusable region
The last 4 MiB of RAM on those devices is likely used by trustzone
firmware, and is unusable under Linux. Change the device tree memory
node accordingly.
The proprietary bootloader (S-BOOT) passes these memory ranges through
ATAG_MEM; this change allows us to have the correct memory ranges
without relying on ATAG_MEM.
