msm: board-9615: Return result from vbus power routine
USB OTG driver maintains the state of VBUS using vbus_is_online flag
for pdata based vbus power routine. Hence remove the used vbus_is_online
flag here and return the result of VBUS power sequence to update the
vbus_is_online flag in OTG driver.
