usb: typec: ucsi: Report power supply changes on power opmode changes

Report opmode changes from the PPM to the power supply class by calling
ucsi_port_psy_changed(). If the current opmode is USB PD, do not call
ucsi_port_psy_changed(). The power supply class will be updated after
requesting partner source PDOs.
