DID: Indicates the ID of the domain whose IOTLB entries need to be selectively
invalidated. This field should be programmed by software for domain-selective and
page-selective invalidation requests.
The Capability register reports the domain-id width supported by hardware. Software
should ensure that the value written to this field is within this limit. Hardware ignores
and not implements bits 47:(32+N), where N is the supported domain-id width
reported in the Capability register.
