Is your enhancement proposal related to a problem? Please describe. See https://github.com/zephyrproject-rtos/zephyr/pull/68431/ Configuring clocks for usb phy on STM32 is confusing due to:

difference between various IP versions
ulpi clock which should be disabled in low power more

Describe the solution you'd like Add clear dts properties to explicit the possible clocks configuration which are expected from the IP. Update both legacy and experimental drivers
