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.
