Samsung DTS ARM changes for v4.20

1. Bring up DSI and HDMI on Exynos5250 Arndale.
2. Use the new way of setting external wakeup interrupts on S5Pv210.
3. Use proper cpufreq suspend OPP to fix suspend/wakeup from RAM on Snow
   Chromebook (Exynos5250).
4. Fully describe regualtors on Odroid XU3-family boards.
5. Fix sound in Snow-rev5 Chromebook.
6. Fix regulators configuration on Peach Pi/Pit Chromebooks (Exynos5420)
   which should be always on.
7. Fix pull control on PMIC interrupt lines on multiple boards which
   essentially fixes waking up by RTC.
8. Add PMIC interrupts on Exynos4210 UniversalC210 board.
9. Add external SD card support for Trats board (Exynos4210).
10. Correct audio subsystem parent clock on Peach Chromebooks.
11. Minor cleanups.
