Subject: [PATCH v3 1/8] dt-bindings: clock: convert hisi-crg.txt to YAML

From: Yang Xiwen <forbidden405@...look.com>

Also rename to hisilicon,hisi-crg.yaml. While at it, add "syscon" and
"simple-mfd" compatibles to match the existing dts.

Add reset-controller subnode for hisilicon,hi3798cv200-crg to match the
existing hi3798cv200.dtsi.
