Enabled lid angle calculation. Clamshell/Tablet mode is decided by lid angle. Accelerometers are set to be active in S3 also. Trackpad is enabled/disabled by GPIO TP_INT_DISABLE. Keyboard scan and trackpad are enabled in clamshell mode and disabled in tablet mode. Removed enable_keyboard() since keyboard is enabled in clamshell S0 and S3. BUG=chrome-os-partner:41353 TEST=Verify in clamshell mode, system can be waken up from S3 by keyboard/trackpad; And not tablet mode.
