[ Upstream commit 4a663dae47316ae8b97d5b77025fe7dfd9d3487f ]
IOASID code is needed by VT-d scalable mode for PASID allocation.
Add explicit dependency such that IOASID is built-in whenever Intel
IOMMU is enabled.
Otherwise, aux domain code will fail when IOMMU is built-in and IOASID
is compiled as a module.
Fixes: 59a623374dc38 ("iommu/vt-d: Replace Intel specific PASID allocator with
IOASID")
