[RFC 16/19] arm64: dts: imx8mq: Add interconnect properties to icc consumer nodes

We add all the properties necessary to control the interconnect
based on the required rates all the way from consumers to the dram.
The fsl,icc-rate specifies the minimum required rate the consumer needs
in order to operate.
For now, only the fec, usdhc1 and usdhc2 are added as consumers.
