usb: typec: tcpm: update power supply once partner accepts
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.
Fixes: f2a8aa053c176 ("typec: tcpm: Represent source supply through power_supply")
