ACPI: sysfs: manage attributes as attribute_group

Browse source

The current manual attribute management is inconsistent and brittle.

Not all return values of device_create_file() are checked and the
cleanup logic needs to be kept up to date manually.

Moving all attributes into an attribute_group and using the is_visible()
callback allows the management of all attributes as a single unit.
