arm64: errata: Add newer ARM cores to the spectre_bhb_loop_affected() lists
commit a5951389e58d2e816eed3dbec5877de9327fd881 upstream. When comparing to the ARM list [1], it appears that several ARM cores were missing from the lists in spectre_bhb_loop_affected(). Add them. NOTE: for some of these cores it may not matter since other ways of clearing the BHB may be used (like the CLRBHB instruction or ECBHB), but it still seems good to have all the info from ARM's whitepaper included.
