ucsi: start usb host mode when partner type is power cable/ufp 



Currently UCSI framework doesn't perform anything in terms of USB role
when partner type is reported as power cable or power cable with ufp
connected. This results into no USB host mode functionality. This is
valid usecase where user wants to use legacy type c power cable with
type a female connector to attach different USB devices like mouse,
thumb drive etc. Hence start USB host mode when partner type is
reported as power cable or power cable with ufp connected.
