Input: add driver for keyboard on AAED-2000 development board (ARM)
The keyboard is connected via GPIOs to the processor, and scanned
using a column sample register. The hardware provides no debouncing
mechanism, so the state of the keys is read KBDSCAN_STABLE_COUNT
times before being reported to the input layer.
The status of the keys needs to be polled because there is no
interrupt hooked to the lines. A workqueue is used for this.
