Added ability to disable the keyboard to wake from suspend when the lid is outside a certain angle range. This has been added to glimmer by defining CONFIG_LID_ANGLE_KEY_SCAN in its board.h. Also modified the lid angle calculation to include a reliability flag which can be used to tell when the hinge aligns too closely with gravity and the lid angle value is unreliable. BUG=none BRANCH=rambi TEST=Tested on a glimmer: In S3, verified that when the lid is open past ~180 deg, the keyboard does not wake the machine. Also verified that if you align hinge with gravity, the keyboard enabled/disabled status remains the same (since we can't actually trust the lid angle value).
