Adds support in the identity mapping feature that allows KVM to setup
identity mapping for the Hyp mode with the AP[1] bit set as required by
the specification and also supports freeing created sub pmd's after
finished use.

These two functions:
  - hyp_identity_mapping_add(pgd, addr, end);
  - hyp_identity_mapping_del(pgd, addr, end);
are essentially calls the same function as the non-hyp versions but
with a different argument value. KVM calls these functions to setup
and teardown the identity mapping used to initialize the hypervisor.

Note, the hyp-version of the _del function actually frees the pmd's
pointed to by the pgd as opposed to the non-hyp version which just
clears them.



These are for mapping host memory, not guest memory, right?
