ARM: dts: reduce total RAM by 22 MiB for exynos5422-odroidxu3

mszyprow · Kukjin Kim · commit 6591a02e17e6 · 2015-01-24T13:24:10.000+09:00
Last 22 MiB is RAM is reserved by secure monitor code and cannot be
accessed from Linux kernel, so adjust total RAM size to 0x7EA00000
(2 GiB - 22 MiB). This fixes random 'imprecise kernel abort' kernel
failures.
