Johan Jonker 398b25003d dt-bindings: mmc: synopsys-dw-mshc: fix clock-freq-min-max in example
A test with the command below does not detect all errors
in combination with 'additionalProperties: false' and
allOf:
  - $ref: "synopsys-dw-mshc-common.yaml#"
allOf:
  - $ref: "mmc-controller.yaml#"

'additionalProperties' applies to all properties that are not
accounted-for by 'properties' or 'patternProperties' in
the immediate schema.

First when we combine synopsys-dw-mshc.yaml,
synopsys-dw-mshc-common.yaml and mmc-controller.yaml it gives
this error:

Documentation/devicetree/bindings/mmc/synopsys-dw-mshc.example.dt.yaml:
mmc@12200000: 'clock-freq-min-max' does not match any of the regexes:
'^.*@[0-9]+$', '^clk-phase-(legacy|sd-hs|mmc-(hs|hs[24]00|ddr52)|
uhs-(sdr(12|25|50|104)|ddr50))$', 'pinctrl-[0-9]+'

'clock-freq-min-max' is deprecated, so replace it by 'max-frequency'.
