Impact: cleanup, reduce kernel size a bit, avoid sparse warning
Fixes sparse warning:
arch/x86/kernel/amd_iommu.c:1299:6: warning: symbol 'prealloc_protection_domains' was not declared. Should it be static?

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.
