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

Browse Source 
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.

domain binding[2].

"fsl,imx8qxp-scu-pd"
followed by "fsl,scu-pd"
