Add new viommu_type field and field values XEN_DOMCTL_CONFIG_VIOMMU_NONE
XEN_DOMCTL_CONFIG_VIOMMU_SMMUV3 in xen_arch_domainconfig to
enable/disable vIOMMU support for domains.
Also add viommu="N" parameter to xl domain configuration to enable the
vIOMMU for the domains. Currently, only the "smmuv3" type is supported
for ARM.
