Samsung DTS ARM changes for v5.11

1. Many cleanups of DTS and alignments to dtschema. Most of them do not
   have any functional effect except passing dtschema checks or dtc W=2
   builds.
2. Fix USB 3.0 ports on Odroid XU board: wrong roles assigned to two
   ports, missing supply to the USB over-current and VBUS control pins
   and finally missing pin configuration for these pins.
3. Switch Exynos5422 DMC driver to monitoring/polling mode, instead of
   using interrupts.
4. Correct the usage of "opp-shared" properties which lead to disabling
   the bus frequency and voltage scaling.
5. Enable Bluetooth on few Exynos4210 and Exynos4412 boards.
6. Enable dual-role USB on Odroid U3+ board.
7. Add Ethernet description in multiple Odroid DTS allowing also easy
   MAC address filling by bootloader.
8. Add Ethernet to Artik 5 (Exynos3250) board.
9. Add interconnect properties to Exynos4412 to fix old Mixer issues.
