Samsung DTS ARM64 changes for v5.20 1. Add CPU cache, UFS to Tesla FSD. 2. Add reboot-mode (boot into specific bootloader mode) to ExynosAutov9. 3. Add watchdogs to ExynosAutov9. 4. Add eMMC to Exynos7885 JackpotLTE (Samsung Galaxy A8). 5. DTS cleanup: white-spaces, node names, LED color/function. 6. Switch to DTS-local header for pinctrl register values instead of bindings header. The bindings header is being deprecated because it does not reflect the purpose of bindings.
