Subject: [PATCH 03/11] iommu: Use Functions to set default domain type in
 iommu_set_def_domain_type()
Patch-mainline: v5.4-rc1
Git-commit: adab0b07cbbc73f9fc338e4fc1749714dd093a7c
References: bsc#1136039

There are functions now to set the default domain type which
take care of updating other necessary state. Don't open-code
it in iommu_set_def_domain_type() and use those functions
instead.
