[RFC 04/19] devfreq: imx-bus: Decouple imx-bus from icc made

[Abel Vesa]

The link between an imx-bus device and its icc id will be done
through the fsl,icc-id property in each dts node. The imx
interconnect driver will pick up all the dts nodes that have that
property defined and will link them to the rightfull icc id.
