usb: pd: policy_engine: Add support to handle floating charger

Browse source 
There is a possibility of PMI detecting SDP as a floating charger
when connected to a PC. Workaround this issue by starting peripheral
stack for floating charger as well. Stop peripheral stack after 10 sec
in absence of USB device enumeration.
