iommu: Hide ops.domain_alloc behind CONFIG_FSL_PAMU
fsl_pamu is the last user of domain_alloc(), and it is using it to create
something weird that doesn't really fit into the iommu subsystem
architecture. It is a not a paging domain since it doesn't have any
map/unmap ops. It may be some special kind of identity domain.
For now just leave it as is. Wrap it's definition in CONFIG_FSL_PAMU to
discourage any new drivers from attempting to use it.
