commit 4050f2683f2c3151dc3dd1501ac88c57caf810ff upstream.
power_supply_changed needs to be called to notify clients after the partner accepts the requested values for the pps case.
Also, remove the redundant power_supply_changed at the end of the tcpm_reset_port as power_supply_changed is already called right after usb_type is changed.
