Imapct: add a new struct member to 'struct protection_domain'
When using protection domains for dma_ops and KVM its better to know for
which subsystem it was allocated. Add a flags member to struct
protection domain for that purpose.

Impact: add a function to flush a domain id on every IOMMU

Impact: save unneeded logic to add and remove domains to the list
The removal of a protection domain from the iommu_pd_list is not
necessary. Another benefit is that we save complexity because we don't
have to readd it later when the device no longer uses the domain.

Impact: split one function into three
The separate functions are required synchronize commands across all
hardware IOMMUs in the system.

Impact: change code to free pagetables from protection domains
The dma_ops_free_pagetable function can only free pagetables from
dma_ops domains. Change that to free pagetables of pure protection
domains.

The iommu_map function maps only one page. Make this clear in the
function name.

These two IOMMUs can implement the current version of this API. So
select the API if one or both of these IOMMU drivers is selected.
