Add the missing forward declarations and includes so it does not have
implicit dependencies. mem_encrypt.h is a public header imported by
drivers. Users should not have to guess what include files are needed.
Resolves a kbuild splat:
In file included from drivers/iommu/generic_pt/fmt/iommu_amdv1.c:15:
