The console adc command prints adc values in the order they appear in hardware, however they are lableled in the order they are enumerated in board.h, which is not necessarily the same. This prints the correct name and value pairs, and removes the adc_read_all_channels function which is not otherwise used. BUG=chromium:571476 BRANCH=None TEST="adc" command associates correct values with names now.
