drivers: usb: stm32: Replace static clock check by a runtime check.
In order to clean up clock related code, replace static build time
clock configuration code by a runtime check.
Since I'm not able to guarantee this check will provide a correct
verdict in 100% of the cases (I'm thinking to ULPI or exotic configurations
like F7 OTG-HS), add a config option to disable it if needed.
It also doesn't apply on F1/F3 series. Keep the build time check for now.
