Subject: [PATCH 02/18] KVM: sefltests: Add kvm_util_types.h to hold common
 types, e.g. vm_vaddr_t

Move the base types unique to KVM selftests out of kvm_util.h and into a
new header, kvm_util_types.h.  This will allow kvm_util_arch.h, i.e. core
arch headers, to reference common types, e.g. vm_vaddr_t and vm_paddr_t.

No functional change intended.
