This is refactoring to enable support for the two USB PHYs available on some STM32F4 processors to be used at the same time. The F405/7 & F429 have two USB PHYs, others such as the F411 only have one PHY. This has been tested separately on a pyb10 (USB_FS PHY) and F429DISC (USB_HS PHY) to be able to invoke a REPL/USB. I have modified a PYBV10 to support two PHYs. The long term objective is to support a 2nd USB PHY to be brought up as a USB HOST, and possibly a single USB PHY to be OTG.
