This adds the application part of alarm wake up. On some targets like the Fuze+, it will also require a bootloader change to make sure that the device doesn't power down on alarm wake up (for example on the Fuze+ the bootloader requires the power button to be hold sufficiently long, thus preventing alarm wake up to work) Change-Id: I5d01957852355fddbd48110d3d75a5533f07879e
