Add typec mode check for charger presence

Browse source 
When usb is in suspend state, the power supply usb
and pc_port will be offline. The demo mode cannot exit
from this situation.
Use typec mode as additional condition check for
charger presence, so that the step charge can keep
in demo mode and handle recharge event.
