usb: phy-msm-usb: Fix reporting of POWER_SUPPLY_PROP_PRESENT



Currently when querying the usb power_supply property for PROP_PRESENT
it returns the value given by PROP_ONLINE, which indicates whether
the USB peripheral has enumerated or not. This is incorrect and should
instead reflect the state of the USB cable connection (VBUS indication)
irrespective of enumeration state.
