The SMC1 block on i.MX7ULP is already used as a clock provider in
imx7ulp.dtsi, but the corresponding dt-binding schema does not define
the required '#clock-cells' property. This results in CHECK_DTBS schema
validation errors.
Functionally, SMC1 controls the CPU run mode configuration:
- 00b: Normal Run (RUN)
- 10b: Very-Low-Power Run (VLPR)
- 11b: High-Speed Run (HSRUN)
These run modes determine the effective CPU operating point, and their
programming is tied to the OPP table.
Add the missing `#clock-cells` definition so the dt-binding schema is
consistent with the DTS and validates correctly.

Allow clocks and clock-names to match existed dts file.
'hsrun_divcore' should be 'hsrun-divcore'. But use '_' to keep old dts back
compatible.
Fix below CHECK_DTBS warnings:
arch/arm/boot/dts/nxp/imx/imx7ulp-com.dtb: clock-controller@40410000 (fsl,imx7ulp-smc1): '#clock-cells', 'clock-names', 'clocks' do not match any of the regexes: '^pinctrl-[0-9]+$'
