[PATCH 1/1] dt-bindings: mmc: fsl,esdhc: Add explicit reference to mmc-controller-common

[Alexander Stein]

Even though it is referenced by mmc/mmc-controller.yaml it still raises
the warning:
  esdhc@1560000 (fsl,ls1021a-esdhc): Unevaluated properties are not allowed ('bus-width' was unexpected)

Adding an explicit reference fixes this.

I don't know if this is a tooling problem or whatever. I would have
expected that mmc-controller-common.yaml is added via
mmc-controller.yaml. But apparently this is missing resulting in the
given warning. Hence adding the reference
