x86-iommu: introduce "intremap" property
Adding one property for intel-iommu devices to specify whether we should
support interrupt remapping. By default, IR is disabled. To enable it,
we should use (take Intel IOMMU as example):
-device intel_iommu,intremap=on
This property can be shared by Intel and future AMD IOMMUs.
