53b3cd2532 fix(cpus): workaround for Cortex-A715 erratum 2331818
Cortex-A715 erratum 2331818 is a cat B erratum that applies to
revisions r0p0 and r1p0 and is fixed in r1p1. The workaround is to
set bit[20] of CPUACTLR2_EL1. Setting this bit is expected to have
a negligible performance impact.

1f73247132 fix(cpus): workaround for Cortex-A715 erratum 2420947
Cortex-A715 erratum 2420947 is a cat B erratum that applies only
to revision r1p0 and is fixed in r1p1. The workaround is to set
bit[33] of CPUACTLR2_EL1. This will prevent store and store-release
to merge inside the write buffer, and it is not expected to have
much performance impacts.

c82fb382b2 refactor(cpus): convert Cortex-A715 to 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 and checking
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.
 * Manual comparison of disassembly of converted functions with non-
   converted functions
 * Build for debug with all errata enabled and step through ArmDS
   at reset to ensure all functions are entered.
