phy: usb: Get all drivers that use USB clks using correct enable/disable
The BRCM USB Phy, ohci, ehci and xhci drivers all use the USB clocks but not all drivers use the clk_prepare_enable/clk_disable_unprepare versions to enable/disable the clocks. This change gets all drivers using the prepare version.
