Currently the usb phy clocks are registered form board files, which will not be called during a device tree based boot. To be able to probe correctly usb form a device tree boot, register the usb phy clocks form the DT specific init. Unfourtunatly, davinci does not have proper clock support on device tree yet, so by registering the clock form de DT specific file we are forced to hardcode the parent clock, and cannot select refclkin as parent for any of the phy clocks of the da850 family. As none of the current da850 based boards currently in mainline use refclkin as source. I guess we can live with this limitation until clocks are correctly represented through CCF/device tree.
