u8800: Fix data.
u8800: Initial list of hardware-specific features.

This list will be updated when new feature is added into the ROM.
u8800: Add libsensors. Add APS-12D light & proximity sensor.

This is the first part of the open source libsensors, with aps-12d
enabled right now.

Notes for aps-12d:
 * Sometimes quirky proximity sensor.
 * Not calibrated light sensor (refer to APSSensor.h).
