Unlike MSM SoC, IPQ SoC doesn't use RPM to aggregate bandwidth
requests and scale the NoC frequency. The NoCs are turned on and
set to a specific frequency at boot time and that is used for the
lifetime of the system. Hence interconnect was not considered
previously.

The same approach was used for PCIe and at that point the
consensus was to move to interconnect. Hence implemented the ICC
driver and updating the existing USB driver to use the ICC
driver.

USB uses icc-clk framework to enable the NoC interface clock.
Hence the 'iface' clock is removed from the list of clocks.
Update the clock-names list accordingly.
