[ Upstream commit 882aa6525cabcfa0cea61e1a19c9af4c543118ac ]
Module device tables need to be declared as maybe_unused because they will be unused when built-in and the corresponding option is also disabled.
This patch adds the maybe_unused attributes to OF and ACPI. This also allows us to remove the ifdef around the ACPI data structure.
