[PATCH v1 43/50] ARM: dts: exynos: add bus_isp in Exynos5422

[Lukasz Luba]

Add bus_isp which changes ACLK400_ISP clock speed according to the bus
documentation in the documentation. The bus_isp OPP table has been
aligned to the new parent rate. This patch sets the proper parent and
picks the init frequency before the devfreq governor starts working.
It sets also parent rate (DPLL to 1200MHz).
