IPQ SoCs dont involve RPM in managing NoC related clocks and there is no NoC scaling. Linux itself handles these clocks. However, these should not be exposed as just clocks and align with other Qualcomm SoCs that handle these clocks from a interconnect provider. Hence include icc provider capability to the gcc node so that peripherals can use the interconnect facility to enable these clocks. Change USB to use the icc-clk framework for the iface clock.
