Samsung DTS ARM changes for v5.6

1. Couple ARM and wcore bus regulators on Exynos542x so higher
   frequencies could be used with dynamic voltage and frequency scaling.
   Enable this higher frequencies.
2. Correct the polarity of USB3503 hub GPIOs.
3. Adjust the bus frequencies (scaled with devfreq framework) on
   Exynos5422 Odroid boards to match values possible to obtain from root
   PLLs.
4. Add display to Tiny4412 board.
5. Cleanups and minor improvements.
