Subject: [PATCH v3 1/1] dt-bindings: remoteproc: imx_rproc: add minItems for power-domain

"fsl,imx8qxp-cm4" and "fsl,imx8qm-cm4" need minimum 2 power domains. Other
platform doesn't require 'power-domain'.

Signed-off-by: Frank Li <Frank.Li@....com>

Notes:
    Change from v2 to v3
    - only imx8qxp and imx8qm need power-domain, other platform don't need it.
    - update commit message.
    
    Change from v1 to v2
    - set minitem to 2 at top
    - Add imx8qm compatible string also
    - use not logic to handle difference compatible string restriction
    - update commit message.
    
    pass dt_binding_check.
