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.
