refactor(cpus): convert Neoverse-N1 to framework

For N1, 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 at reset or runtime
  - The epilogue with the workaround_<type>_end
  - The checker function with the check_erratum_<type> to check whether
    the erratum applies on the revision of the CPU.

Testing was conducted by:
  - 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 debug with all errata enabled and step through ArmDS
    to ensure all functions are entered and the path remains the same
    as before conversion to the new framework.
