During typical gadget operation, dwc2 clock was enabled 3 times: from
dwc2_gadget_init(), dwc2_hsotg_udc_start() and dwc2_hsotg_pullup(), and
then disabled in s3c_hsotg_pullup(), s3c_hsotg_udc_stop() and
dwc2_hsotg_remove(). This really makes no sense, so leave clock control
code only in dwc2_gadget_init/remove functions.
