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: 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.
