dt-bindings: phy: phy-stm32-usbphyc: add #clock-cells property
usbphyc provides a unique clock called ck_usbo_48m.
STM32 USB OTG needs a 48Mhz clock (utmifs_clk48) for Full-Speed operation.
ck_usbo_48m is a possible parent clock for USB OTG 48Mhz clock.
ck_usbo_48m is available as soon as the PLL is enabled.
