typec: disable vbus under 0.8V interrupt when vbus remove

Browse source 
As vbus remove and type-c cable still inserted at BSP test, the
CC voltage transfer to VBUS pin, the vbus pin voltage range is 0~1.25V
frequent switch. So the interrupt of vbus under 0.8V is triggered frequently.
So disable this interrupt when vbus remove.
