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.

Add bindings documentation for Exynos PMU hardware block. It was taken
from Linux kernel [1], but minimized and modified to reflect features
that will be actually supported in U-Boot soon. For example,
the "samsung,uart-debug-1" property is not available in Linux kernel
bindings and only present in U-Boot.

Add USI bindings documentation and header file. Those are taken from
Linux kernel [1,2], but the documentation was reworked a bit to only
describe the compatibles that will be supported in U-Boot soon.

Series-changes: 3
- revert:
commit "3374264df97b" ("drivers: net: qe: deselect QE when DM_ETH is enabled")
as now qe works with DM and DM_ETH support.
- fix mailaddress from Holger
Series-changes: 2
- add comments from Qiang Zhao:
- add device node documentation
- I did not drop the dm_qe_uec_phy.c and use drivers/net/fsl_mdio.c
because using drivers/net/fsl_mdio.c leads in none existent
udevice mdio@3320
instead boards with DM ETH support should use now this
driver.
- remove RFC tag
Commit-notes:
- I let the old none DM based implementation in code
so boards should work with old implementation.
This Code should be removed if all boards are converted
to DM/DTS.
- add the DM based qe uec driver under drivers/net/qe
- Therefore copied the files uccf.c uccf.h uec.h from
drivers/qe. So there are a lot of Codingstyle problems
currently. I fix them in next version if this RFC
patch is OK or it needs some changes.
- The dm based driver code is now under drivers/net/qe/dm_qe_uec.c
Used a lot of functions from drivers/qe/uec.c
- seperated the PHY specific code into seperate file
drivers/net/qe/dm_qe_uec_phy.c
