Update the RCC stm32mp1 clock driver to handle the USB_PHY_48
clock provided by USBPHYC and named "ck_usbo_48m".

With this series, the clock dependencies for USB PHYC, USBOTG (including
USB detection) and USBHOST are correctly managed.

See Linux kernel commit "ARM: dts: stm32: use usbphyc ck_usbo_48m as USBH
OHCI clock on stm32mp151" and "phy: stm32: register usbphyc as clock
provider of ck_usbo_48m clock"
