Use upstream device tree files and bindings. To do so:
- imply (enable) OF_UPSTREAM option for E850-96 target
- point DEFAULT_DEVICE_TREE in E850-96 config to upstream dts
- remove now not needed local dts files, binding docs and headers
- update MAINTAINERS correspondingly
Upstream device tree files for Exynos850 SoC and E850-96 board are pretty much the same as local (removed) ones, so the conversion is rather straightforward and painless in this case. The appended dts file (arch/arm/dts/exynos850-e850-96-u-boot.dtsi) stays unchanged.
The only remaining local dt-bindings doc for E850-96 board is exynos-pmu.yaml. It wasn't removed as it's quite different from Linux kernel version. Particularly U-Boot local version of exynos-pmu.yaml describes "samsung,uart-debug-1" property, which is not present in Linux kernel binding. Later it might be upstreamed to Linux kernel, and once it's done the U-Boot exynos-pmu.yaml binding can be removed.
No functional change.

Thanks, Sumit! I forgot to update board/samsung/e850-96/MAINTAINERS, so I'll be sending v2 shortly.
