This change modifies the behavior of RBOX by blocking the key0 and key1 output, when the power button is pressed. It also adds support for printing debug statements when various RBOX interrupts are triggered. BUG=none BRANCH=none TEST=On cr50 test board verify key0 and key1 out are not asserted unless the power button is pressed.
