ARM: dts: samsung: exynos5420-galaxy-tab: decrease available memory

The last 6 MiB are used by trustzone firmware, and cannot be used by
Linux.  Currently we are saved by that the proprietary bootloader
(sboot) passes available memory to kernel through ATAG_MEM.  Change
memory range in any case so that we do not have to rely on ATAG_MEM.
