> "iommu/vt-d: Audit IOMMU Capabilities and add helper functions", aiming
> to verify the consistency of capabilities across all IOMMUs for supported
> features.
> 
> Nowadays, all the kAPIs of the iommu subsystem have evolved to be device
> oriented, in preparation for supporting heterogeneous IOMMU architectures.
> There is no longer a need to require capability consistence among IOMMUs
> for any feature.

> Remove the iommu cap audit code to make the driver align with the design
