refactor(cpus): convert the Cortex-A72 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.

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.

* Testing via script was not complete, as it directed to verify the
check and the workaround functions of few erratas manually.

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

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

* Manual comparison of disassembly of both both files(bl31.elf)
ensured,the ported changes were identical and hence verified.

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

* Build for debug with all errata enabled and step through ArmDS

functions are entered precisely.
