dt-bindings: power: Add fsl,scu-pd yaml file 



In order to replace the fsl,scu txt file from bindings/arm/freescale,
we need to split it between the right subsystems. This patch documents
separately the 'power controller' child node of the SCU main node.

Power domain bindings based on SCU Message Protocol

------------------------------------------------------------



This binding for the SCU power domain providers uses the generic power

domain binding[2].



Required properties:

- compatible:		Should be one of:

			  "fsl,imx8qm-scu-pd",

			  "fsl,imx8qxp-scu-pd"

			followed by "fsl,scu-pd"



- #power-domain-cells:	Must be 1. Contains the Resource ID used by

			SCU commands.

			See detailed Resource ID list from:

			include/dt-bindings/firmware/imx/rsrc.h
