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.

* tag 'samsung-dt-5.6' of https://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux:
  ARM: dts: exynos: Enable FIMD node and add proper panel node to Tiny4412
  ARM: dts: samsung: Rename Samsung and Exynos to lowercase
  ARM: dts: exynos: Adjust bus related OPPs to the values correct for Exynos5422 Odroids
  ARM: dts: exynos: Move Exynos5420 bus related OPPs to the Odroid boards DTS
  ARM: dts: exynos: Correct USB3503 GPIOs polarity
  ARM: dts: exynos: Add missing CPU frequencies for Exynos5422/5800
  ARM: dts: exynos: Add initial data for coupled regulators for Exynos5422/5800
  ARM: dts: exynos: Remove syscon compatible from chipid node on Exynos5
