usb: musb: drop a gigantic amount of ifdeferry
the MUSB IP is always OTG, so there's no point in adding so many ifdefs on the code. Drop those and always compile the driver for OTG support. This also allows us to drop the useless "driver mode" choice. For doing that, we need to make musb depend on both Host and Peripheral side.
