iommu/mediatek-v1: Tidy up probe_finalize

Krzysztof points out that although the driver now supports COMPILE_TEST
for other architectures, it does not build cleanly with W=1 where the
stubbed-out ARM API can lead to an unused variable warning.

Since this is effectively the correct intent of the code in such cases,
mark it as __maybe_unused, tidying up some cruft in the process.
