iommu/amd: Factor out helper for manipulating IRTE GA/CPU info

Browse source

Split the guts of amd_iommu_update_ga() to a dedicated helper so that the
logic can be shared with flows that put the IRTE into posted mode.

Opportunistically move amd_iommu_update_ga() and its new helper above
amd_iommu_activate_guest_mode() so that it's all co-located.
