IOMMU: Add two generic functions to vendor neutral interface

Add 2 generic functions into the vendor neutral iommu interface, The
reason is that from changeset 19732, there is only one global flag
"iommu_enabled" that controls iommu enablement for both vtd and amd
systems, so we need different code paths for vtd and amd iommu systems
if this flag has been turned on. Also, the early checking of
"iommu_enabled" in iommu_setup() is removed to prevent iommu
functionalities from been disabled on amd systems.
