refactor(cpus): convert the Cortex-A510 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. Note: cortex_a510.S is applicable and being used only by arm_fpga platform. However, to test the ported changes, below steps were carried out on the fvp and the obtained results has been verified. 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.
