ACPI: TAD: Use dev_groups in struct device_driver

Instead of creating and removing the device sysfs attributes directly
during probe and remove of the driver, respectively, use dev_groups in
struct device_driver to point to the attribute definitions and let the
core take care of creating and removing them.

No intentional functional impact.
