refactor(cpus): convert the Cortex-A77 to use the errata framework

This involves replacing:
 * the reset_func with the standard cpu_reset_func_{start,end} to apply
   errata automatically
 * the <cpu>_errata_report with the errata_report_shim to report errata
   automatically
...and for each erratum:
 * the prologue with the workaround_<type>_start to do the checks and
   framework registration automatically
 * the epilogue with the workaround_<type>_end
 * the checker function with the check_erratum_<type> to make it more
   descriptive

It is important to note that the errata workaround sequences remain
unchanged and preserve their git blame.
