drivers: usb stm32H5 and stm32U5 have an independent power supply

The stm32H5 mcu has an independent USB supply to be enabled
at init with LL_PWR_EnableVDDUSB function like the stm32U5 serie.
Both series have PWR_USBSCR_USB33SV bit in their USBSCR POWER reg.
and other series all have PWR_CR2_USV bit in their CR2 POWER reg.
