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.
