It is not a USB controller's clock, it is one USB device's clock which
uses SoC clock at one specific board. Currently, there is only one general
USB HUB driver, no any special board information in it. 

You can also put this special board control at arch/arm/mach-imx/mach-imx6q.c
if shawn also agree it.
