[PATCH 3/3] iommu/vt-d: Add build dependency on IOASID

From: Jacob Pan
Date: Fri Mar 20 2020 - 00:27:03 EST


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.
