eeepc-laptop: set acpi_driver.owner

The owner field provides the link between drivers and modules in sysfs,
but no ACPI driver was setting it.

After setting the owner field, we can see which module provides which
driver and vice versa by looking at /sys/bus/acpi/driver/*/module and
/sys/module/*/drivers/acpi:*.
