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.
