With the new common clock infrastructure, the following clocks should be
used on i.MX drivers: ipg, per and ahb.
Adapt fsl_mxc_udc to follow this new behaviour to fix the following probe error:
Freescale High-Speed USB SOC Device Controller driver (Apr 20, 2007)
fsl-usb2-udc fsl-usb2-udc: clk_get("usb") failed
fsl-usb2-udc: probe of fsl-usb2-udc failed with error -2

Same question, it looks like copy-paste error...
