[PATCH v1 09/13] phy: stm32-usbphyc: manage properly the clk identifier with CCF

From: Patrick Delaunay <patrick.delaunay at foss.st.com>
Add private uclass data for "stm32-usbphyc-clk" as it is not done
by the driver model.
This clk struct is needed by CCF to save the unique id used to identify
each clock.
