Fix u-host Wi-Fi and OTG USB parameters

I tested the current fex for the u-host and found that it wasn't picking up the OTG port in host mode or finding the usb Wi-Fi chipset. Pulled up my old shared work from mk802ii and the u-host/OE and dumps of the uhost roms and added back the working code. Might push some more changes later as well if they prove useful in any way.
