iommu: Move IOMMU_DOMAIN_BLOCKED global statics to ops->blocked_domain
Following the pattern of identity domains, just assign the BLOCKED domain
global statics to a value in ops. Update the core code to use the global
static directly.
Update powerpc to use the new scheme and remove its empty domain_alloc
callback.
