Add missing 2000MHz & 1900MHz OPPs (for A15 cores) and 1400MHz OPP (for A7 cores). Also update common Odroid-XU3 Lite/XU3/XU4 thermal cooling maps to account for new OPPs.
Since new OPPs are not available on all Exynos5422/5800 boards modify dts files for Odroid-XU3 Lite (limited to 1.8 GHz / 1.3 GHz) & Peach Pi (limited to 2.0 GHz / 1.3 GHz) accordingly. Tested on Odroid-XU3 and XU3 Lite.
