usb: typec: ucsi: psy: Add power supply status

Browse source

Add support for power supply status. If a port is acting as a sink
with the sink path enabled, report it is charging. If a port is
source, report it is discharging. If there is no connection or the
port hasn't enabled the sink path, report not charging.
