iommu: qcom: annotate PM functions as __maybe_unused
The qcom_iommu_disable_clocks() function is only called from PM
code that is hidden in an #ifdef, causing a harmless warning without
CONFIG_PM:
drivers/iommu/qcom_iommu.c:601:13: error: 'qcom_iommu_disable_clocks' defined but not used [-Werror=unused-function]
static void qcom_iommu_disable_clocks(struct qcom_iommu_dev *qcom_iommu)
drivers/iommu/qcom_iommu.c:581:12: error: 'qcom_iommu_enable_clocks' defined but not used [-Werror=unused-function]
static int qcom_iommu_enable_clocks(struct qcom_iommu_dev *qcom_iommu)
Replacing that #ifdef with __maybe_unused annotations lets the compiler
drop the functions silently instead.
Fixes: 0ae349a0f33f ("iommu/qcom: Add qcom_iommu")
