The ID detection and charging circuits on Spring are very different from that on Kirby. PWM current limit is no longer used. The ID detection sequence is also different. Also, there is no boost circuit on Kirby. Given those hardware issues that we had to work around on Spring, it's unlikely that we will have another board that shares the same/similar ID detection design with Spring. Let's rename extpower_usb to extpower_spring to better reflect this. BUG=None TEST=Build and boot Spring.
