Since commit d2e1a003af56 ("ACPI/IORT: Don't call iommu_ops->add_device
directly"), we use the IOMMU core API to replace a direct invoke of the
specified callback. The parameter @ops has therefore became unused. Let's
drop it.

inline functions iort_fwspec_iommu_ops() and iort_add_device_replay()
are not needed anymore after commit 8212688600ed ("ACPI/IORT: Fix build
error when IOMMU_SUPPORT is disabled"), could you please add another
patch to remove them as well?
Thanks

Sure, I will remove them in v2. Thanks for the reminder.
