This is arm64 only so it should really just be enabled in
common/generic/arm/aarch64/ and the option to disable it can be removed as
it's already common/generic/CONFIG_VIRTIO_IOMMU and actually doesn't need to
be there at all being explicitly an arm64 feature.

[OS-BUILD PATCH] redhat/configs: Set CONFIG_VIRTIO_IOMMU on aarch64

[Eric Auger (via Email Bridge)]

From: Eric Auger 

redhat/configs: Set CONFIG_VIRTIO_IOMMU on aarch64

Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1972795

Upstream Status: RHEL only
Tested: on ARM with qemu (Jean-Philippe Brucker's qemu branch as the
qemu integration is not yet upstream)

We want to support the virtio-iommu on ARM. So let's compile it.
