usb: ehci-generic: don't probe fail if there is no clk_enable() ops
Some clock driver do not have a clk_enable() call back, and we should not treat this as fail in ehci probe like other modules, eg. clk_enabl_bulk() do not return fail if ret value is '-ENOSYS' Signed-off-by: Kever Yang <kever.yang@rock-chips.com> Reviewed-by: Patrice Chotard <patrice.chotard@st.com>
