Add a dedicated function to query debug action to board_api

Browse Source 
On the devices where we have only 2 physical buttons, one of those buttons
(i.e. POWER) is connected directly to PMU. The other button (AUX) is
connected directly to S3C pin and we can get its state immediately, it is
currently used to skip a boot possibility. To allow user to debug boot
problems we can use the POWER button, but we cannot poll for it too many
times as it slows down the boot considerably, therefore a dedicated
function is needed.
