[PATCH 0/4] Pegatron Lucid tablet acceleromter/ALS

Resubmission and update of the Pegatron Lucid tablet accelerometer and
ambient light sensor drivers.

Patches 1-3 are against asus-laptop, and apply in order.

Patch 4 is against input, and can be commited separately (obviously
relies on the detection code in asus-laptop at runtime, but will build
and load independently).
