USB: PHY: msm: Clear A_BUS_SUSPEND on cable disconnect



A_BUS_SUSPEND is set on device mode bus-suspend and
cleared on bus-resume. But, bus-resume may not happen
if cable disconnect happens in suspend. This results
in LPM sequence executing as if LPM on bus-suspend is
triggered. Fix this by clearing A_BUS_SUSPEND after
stopping peripheral mode which happens before low
power mode routine is executed.
