From: Rick Edgecombe <rick.p.edgecombe@intel.com>

In future changes coco specific code will need to call kvm_tdp_map_page()
from within their respective gmem_post_populate() callbacks. Export it
so this can be done from vendor specific code. Since kvm_mmu_reload()
will be needed for this operation, export its callee kvm_mmu_load() as
well.
