Commit Message

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 and board/samsung/e850-96/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.

Changes in v2:
  - Updated board/samsung/e850-96/MAINTAINERS (removed board dts entry)
  - Added "Acked-by" tag by Sumit Garg

-description: |
-  Exynos850 clock controller is comprised of several CMU units, generating
-  clocks for different domains. Those CMU units are modeled as separate device
-  tree nodes, and might depend on each other. Root clocks in that clock tree are
-  two external clocks:: OSCCLK (26 MHz) and RTCCLK (32768 Hz). Those external
-  clocks must be defined as fixed-rate clocks in dts.
-
-  CMU_TOP is a top-level CMU, where all base clocks are prepared using PLLs and
-  dividers; all other leaf clocks (other CMUs) are usually derived from CMU_TOP.
-
-  Each clock is assigned an identifier and client nodes can use this identifier
-  to specify the clock which they consume. All clocks available for usage
-  in clock consumer nodes are defined as preprocessor macros in
-  'dt-bindings/clock/exynos850.h' header.

-title: Samsung's Exynos USI (Universal Serial Interface)
-
-maintainers:
-  - Sam Protsenko <semen.protsenko@linaro.org>
-
-description: |
-  USI IP-core provides selectable serial protocol (UART, SPI or High-Speed I2C).
-  USI shares almost all internal circuits within each protocol, so only one
-  protocol can be chosen at a time. USI is modeled as a node with zero or more
-  child nodes, each representing a serial sub-node device. The mode setting
-  selects which particular function will be used.
