[PATCH 2/2] arm64: dts: exynos5433: Add cpu cache information

[Alim Akhtar]

This patch adds cpu caches information to its dt
nodes so that the same is available to userspace
via sysfs.
This SoC has 48/32 KB I/D cache for each A57 cores
with 2MB L2 cache.
And 32/32 KB I/D cache for each A53 cores with
256KB L2 cache.
