crypto: qcom-rng - Fix qcom_rng_of_match unused warning
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.
