Move external power detect for link to its own file
Now that it doesn't need to leverage SWITCH_TASK to send the AC_CHANGE
notification, pure GPIO-based external power detection can move from

BUG=chrome-os-partner:18256
BRANCH=none
TEST=add AC power, UI shows charging indicator; remove AC, indicator goes away
