dt-bindings: writing-schema: Install from PyPI repository
Installing dtschema from github.com/devicetree-org is not needed anymore
because dtschema is now part of regular PyPI repository. In certain
cases it might cause some troubles as it brings latest master version,
not the stable release:
$ pip3 show dtschema
Version: 2020.8.2.dev4+g341f3e3
$ make dt_binding_check
dtschema minimum version is v2020.8.1
