According to the fsl,imx7ulp-pm.yaml binding, clock-controller@40410000 is
not a clock provider. Remove the #clock-cells property to fix the following
CHECK_DTBS warning:
 clock-controller@40410000 (fsl,imx7ulp-smc1): '#clock-cells' does not match any of the regexes: '^pinctrl-[0-9]+$'

Need to fix binding, this is a clock controller and needs #clock-cells to work
properly.

Thanks, strange no one reference label "smc1"

There is a driver for this compatible:
