Douglas Anderson 4117975672 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.
