dt-bindings: mmc: fsl-imx-mmc: Document the required clocks

The fsl-imx-mmc hardware needs two clocks to operate: ipg and per.

Document these required clocks.

This fixes the following schema warning:

imx27-apf27dev.dtb: mmc@10014000: Unevaluated properties are not allowed ('clock-names', 'clocks' were unexpected)
	from schema $id: http://devicetree.org/schemas/mmc/fsl-imx-mmc.yaml#
