Up to this point, the USB phy clock configuration was handled manually in
the board files and in the usb drivers. This adds proper clocks so that
the usb drivers can use clk_get and clk_enable and not have to worry about
the details. Also, the related code is removed from the board files.

You should be able to use IO_ADDRESS(), no?
