arm64: trans_pgd: hibernate: Add trans_pgd_copy_el2_vectors

Browse source 
Users of trans_pgd may also need a copy of vector table because it is
also may be overwritten if a linear map can be overwritten.

Move setup of EL2 vectors from hibernate to trans_pgd, so it can be
later shared with kexec as well.
