arm64: entry: Add non-kpti __bp_harden_el1_vectors for mitigations
commit aff65393fa1401e034656e349abd655cfe272de0 upstream.
kpti is an optional feature, for systems not using kpti a set of
vectors for the spectre-bhb mitigations is needed.
Add another set of vectors, __bp_harden_el1_vectors, that will be
used if a mitigation is needed and kpti is not in use.
The EL1 ventries are repeated verbatim as there is no additional
work needed for entry from EL1.
