USB: dwc3: otg: Turn off VBUS before removing hcd
Currently turning off VBUS is done after removing hcd when
micro A cable is disconnected. Removing hcd might take time for
processing device disconnect and during this time, PMIC will
not notify VBUS valid event if micro B cable is connected. This
results in USB cable not getting detected. Hence turn off VBUS
before removing hcd so that PMIC will notify VBUS events.
