refactor(cpus): convert Neoverse V1 to 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.

Testing was conducted by:

 * Building for release with all errata flags enabled and running script
   in change 19136 to compare output of objdump for each errata. Only
   able to verify the check functions this way, rest had to manually
   verified

 * Manual comparison of disassembly of converted functions with non-
   converted functions

   aarch64-none-elf-objdump -D <trusted-firmware-a with conversion>/build/fvp/release/bl31/bl31.elf
     vs
   aarch64-none-elf-objdump -D <trusted-firmware-a clean repo>/build/fvp/release/bl31/bl31.elf

 * Build for release with all errata flags enabled and run default tftf
   tests
