Some new devices have extra keys, which we add to our list. Currently,
they all generate events that allow us to use a simple table/array,
without need for the sparse keymap.

Instead of a MODULE_DEVICE_TABLE for every acpi_driver ids table, we
create a table containing all ids to export to get a module alias for
each one.

This will fix automatic loading of the driver when one of the ACPI
devices is not present (like the accelerometer, which is not present in
some models).

This add supports for devices like keyboard, backlight, tablet and
accelerometer.
