[PATCH 2/5] dt-bindings: dma: fsl-mxs-dma: Add compatible string "fsl,imx8qxp-dma-apbh"

Add compatible string "fsl,imx8qxp-dma-apbh". It requires power-domains
compared with "fsl,imx28-dma-apbh".

Allow 'power-domains' property because i.MX8DXL i.MX8QM and i.MX8QXP need
it.

Keep the same restriction about 'power-domains' for other compatible
strings.
