I wonder if we can merge it into the exist imx7ulp pm binding doc.
Documentation/devicetree/bindings/arm/freescale/fsl,imx7ulp-pm.yaml

Can we change to the exist naming pattern which also align with HW reference manual?
e.g.
fsl,imx7ulp-pmc0
fsl,imx7ulp-pmc1

Aligned with:
fsl,imx7ulp-smc1
fsl,imx7ulp-pcc2
fsl,imx7ulp-scg1
