Allow 'power-domains' property because i.MX8DXL i.MX8QM and i.MX8QXP need
it.
Fixed below DTB_CHECK warning:
dma-controller@599f0000: Unevaluated properties are not allowed ('power-domains' was unexpected)
Signed-off-by: Frank Li <Frank.Li@xxxxxxx>

Notes:
Change from v1 to v2
- using maxitem: 64. Each channel have one power domain. Max 64 dmachannel.
- add power-domains to 'required' when compatible string is fsl,imx8qm-adma
or fsl,imx8qm-edma
