Add GPIO get/set commands
Signed-off-by: Randall Spangler <rspangler@chromium.org>
BUG=chrome-os-partner:7528
TEST=from debug console,
gpioget --> prints current level. Run a few times to see DEBUG_LED
value toggle.
gpioset debug_led 1 --> turns debug LED on. Run repeatedly to
override the idle task toggling it off.
