stmhal: Enable two USB phys to be supported together.
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.pull/1695/head
