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.
