[PATCH] usb: gadget: s3c-hsotg: fix phy disable sequence

s3c_hsotg_udc_stop. s3c_hsotg_udc_stop is called from udc-core.c only after usb_gadget_disconnect, which in turn calls s3c_hsotg_pullup, which already calls s3c_hsotg_phy_disable. s3c_hsotg_remove must be called only after udc_stop, so there is no point in disabling phy once again there.
