[PATCH V7 1/3] dt-bindings: fsl: scu: make power domain compatible string SoC specific

[PATCH V7 1/3] dt-bindings: fsl: scu: make power domain compatible string SoC specific

[A.s. Dong]

As the power domain API might change in the future for new SoCs, although
in a very low possibility, it's still better to make the compatible string
more SoC specific to avoid the possible version change for new SoCs.

Due to there're still no users in kernel, it's safe to update it without
breaking anything.
