[RFC PATCH v2 03/10] iommu/amd: Add default branch in amd_iommu_capable()

[Lu Baolu <baolu.lu@xxxxxxxxxxxxxxx>]

Otherwise, there will be a build warning:

drivers/iommu/amd_iommu.c:3083:2: warning: enumeration value
'IOMMU_CAP_AUX_DOMAIN' not handled in switch [-Wswitch]

There is no functional change.
