ARM: dts: Extend existing CPU OPP for exynos5800
Fix CPU operating points for Exynos5800 (it use different
voltages than Exynos5420 and supports additional frequencies).
However don't use 2000MHz & 1900MHz OPPs (for A15 cores) and
1400MHz OPP (for A7 cores) for now as they are not available
on all boards.
Based on Hardkernel's kernel for ODROID-XU3 board.

- Port to operating-points-v2
