hwdb: add support for Alienware graphics amplifier

Unplugging and plugging in the cable will create various scancodes
on the keyboard controller.

Userspace within X should be able to interact with these to show
interesting messages. Assign them to generic prog1/prog2.

(David: add comment to hwdb explaining that these keycodes are reserved)
