usb: dwc3-msm: Use PROP_INPUT_CURRENT_LIMIT to for vbus_draw



The charger driver expects USB to indicate the amount of VBUS
current to draw while in peripheral mode using the power_supply
property POWER_SUPPLY_PROP_INPUT_CURRENT_LIMIT instead of
POWER_SUPPLY_PROP_CURRENT_MAX, as the latter is intended as a
read-only property which indicates the actual maximum current
that the charger HW is allowed to draw.
