ARM: dts: exynos: Add CPU OPPs for Exynos4412 Prime
Add CPU operating points for Exynos4412 Prime (it supports additional 1704MHz & 1600MHz OPPs and 1500MHz OPP is just a regular non-turbo OPP on this SoC). Also update relevant cooling maps to account for new OPPs. ODROID-X2/U2/U3 boards use Exynos4412 Prime SoC version so update their board files accordingly. Based on Hardkernel's kernel for ODROID-X2/U2/U3 boards.
