ACPI/IORT: Fix build when CONFIG_IOMMU_API=n
Commit 8097e53eaba2 ("ACPI/IORT: Use helper functions to access dev->iommu_fwspec") changed by mistake the iort_fwspec_iommu_ops() stub definition (compiled in when CONFIG_IOMMU_API=n), that caused the following compilation failure: drivers/acpi/arm64/iort.c:880:1: error: expected identifier or '(' before '{' token { return NULL; } ^ drivers/acpi/arm64/iort.c:879:39: warning: 'iort_fwspec_iommu_ops' used but never defined static inline const struct iommu_ops *iort_fwspec_iommu_ops(struct device *dev); ^~~~~~~~~~~~~~~~~~~~~ Fix it.
