When CONFIG_OF=n of_match_device() gets pre-processed out of existence
leaving qcom-smmu_client_of_match unused. Mark it as possibly unused to
keep the compiler from warning in that case.
Fixes: 0e764a01015d ("iommu/arm-smmu: Allow client devices to select direct mapping")

Thanks. Joerg -- can you pick this one up, please? I don't have any other
SMMU fixes pending at the moment.

I can't see this in Joerg's tree or in linux-next. Joerg: did you pick this
one up? (I thought you did, but I can't find it!).
