[PATCH v2 10/20] KVM: Move {g,p}fn <=> {g,h}pa conversion helpers to kvm_types.h

[Sean Christopherson]

Move the helpers to convert between pfns and physical addresses (for host
and guest) into kvm_types.h so that they can be used throughout kvm_host.h
(and any other KVM-related header) without having to worry about ordering.

No functional change intended.
