Subject: [PATCH v2 1/2] ACPI/IORT: Drop the unused @ops of iort_add_device_replay()

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.
