phy: rockchip-usb: fix clock get-put mismatch
Currently the phy driver only gets the optional clock reference but
never puts it again, neither during error handling nor on remove.
Fix that by moving the clk_put to a devm-action that gets called at
the right time when all other devm actions are done.
