Modules registering driver with acpi_bus_register_driver() often forget to
set .owner field.  The field is used by some of other kernel parts for
reference counting (try_module_get()), so it is expected that drivers
will set it.

Solve the problem by moving this task away from the drivers to the core
ACPI bus code, just like we did for platform_driver in
commit 9447057e ("platform_device: use a macro instead of
platform_driver_register").
