servo_v4: clear SrcCap on CHG port disconnected
Currently, when CHG port's PD disconnected from the servo-v4,
it still holds the SourceCap information. This CL clears the
SourceCap when the PD disconnection event is found.
BUG=b:157261654
TEST=plug charger:
> ada_srccaps
0: 5000mV/3000mA
1: 9000mV/3000mA
2: 15000mV/3000mA
3: 20000mV/2250mA
unplug charger:
> ada_srccaps # print nothing.
