David Hendricks 1f091487b2 snow/stm32: re-configure power LED on the fly (input vs. pwm) ...

Usually the power LED is driven by the PWM mode so that its nominal
brightness can be set to a "soft" on value. However, when
the LED is to remain off the LED should be switched to floating
input mode. This reduces voltage leakage.

This CL updates the power_led_task to configure the LED however is
appropriate and adds board functions to re-configure the GPIO.

BRANCH=snow
BUG=chrome-os-partner:12381
TEST=LED responds as expected in suspend and on/off states, also
tested that leakage is reduced with multimeter
