classmate-laptop: use a single MODULE_DEVICE_TABLE to get correct aliases
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).
