Copy dts/upstream/src/arm64/Makefile into dts/upstream/src/arm/Makefile
and create a commit. This makes 32bit ARM buildable with OF_UPSTREAM .

Allow platform owners to mirror devicetree files from devitree-rebasing
directory into dts/upstream/src/$(ARCH) (special case for arm64). Then
build then along with any *-u-boot.dtsi file present in arch/$(ARCH)/dts
directory. Also add a new Makefile for arm64.
This will help easy migration for platforms which currently are compliant
with upstream Linux kernel devicetree files.

This adds the build infrastructure for checking DT binding schema
documents and validating dtb files using the binding schema. Here we use
devicetree-rebasing subtree to provide the DT bindings. Along with that
adapt dts/upstream/Bindings/Makefile to align with old U-Boot Kbuild
infrastructure.
Dependency:
-----------
The DT schema project must be installed in order to validate the DT schema
binding documents and validate DTS files using the DT schema. The DT schema
project can be installed with pip::
pip3 install dtschema
Note that 'dtschema' installation requires 'swig' and Python development
files installed first. On Debian/Ubuntu systems::
apt install swig python3-dev
Testing:
--------
Build dts files and check using DT binding schema:
$ make dtbs_check
Optionally, DT_SCHEMA_FILES can be passed in with a schema file(s) to
use for validation. This makes it easier to find and fix errors
generated by a specific schema.
Note, at this point dtbs_check is an optional build target as there are
many warnings generated due to custom DT properties used by many
platforms in u-boot. It is expected with these checks that compliance
with DT bindings to take place. Once that's done it can be added to CI
builds to remain compliant with DT bindings.
