[PATCH AUTOSEL 4.19 01/10] crypto: qcom-rng - Fix qcom_rng_of_match unused warning

From: Herbert Xu <herbert@xxxxxxxxxxxxxxxxxxx>

[ 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.
