Subject: [PATCH v1 35/50] ARM: dts: exynos: change speed and parent of NoC
 clock in Exynos5420

This patch changes speed and parent of NoC WCORE bus to 400MHz. The clock
is now attached to a branch were the root is the DPLL which speed is set to
1200MHz. The OPPs are aligned to this rate accordingly.
