AMD/IOMMU: introduce a "valid" flag for IVRS mappings

For us to no longer blindly allocate interrupt remapping tables for
everything the ACPI tables name, we can't use struct ivrs_mappings'
intremap_table field anymore to also have the meaning of "this entry
is valid". Add a separate boolean field instead.
