Update the Poseidon CPU variant name to "POSEIDON VNAE" in alignment
with the MIDR 0x410FD830. This adjustment reflects the accurate
designation for the default Poseidon CPU and allows for seamless support
of other variants in the future.

Cortex X3 erratum 2743088 is a Cat B erratum that applies to all

The TAM bits of CPTR_EL2 and CPTR_EL3 are incorrectly set in the reset
handling sequence of the Neoverse N2 CPU. As these bits are set, any
access of AMU registers from EL0/EL1 and EL2 respectively are
incorrectly trapped to a higher EL. Fix this by clearing the TAM bits in
both the CPTR_EL2 and CPTR_EL3 registers.

The DSU contains system control registers in the SCU and L3 logic to
control the functionality of the cluster. If "DIRECT CONNECT" L3 memory
system variant is used, there won't be any L3 cache, snoop filter, and
SCU logic present hence no system control register will be present.
Hence check SCU presence before accessing DSU register for DSU_2313941
errata.

Neoverse V2 erratum 2719105 is a Cat B erratum that applies to all

The erratum is avoided by setting CPUACTLR2_EL1[0] to 1 to force

refactor(cpus): convert the Cortex-A53 to use cpu helpers
refactor(cpus): convert the Cortex-A53 to use the errata framework
refactor(cpus): reorder Cortex-A53 errata by ascending order
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.
At this point the binary output of all errata was checked with the
script from commit 19136. All reported discrepancies involve errata
with no workaround in the cpu file or errata that did not previously
have a workaround function and now do. The non temporal hint erratum has
been converted to a numeric erratum.

Also, convert checker functions of errata which are enabled for all cpu
revisions to report correctly in preparation of the errata ABI.
Although the script from commit 250919 was used to check that errata
code did not change, this CPU only loosely adhered to convention and its
output was not particularly useful. Nevertheless, the discrepancies were
manually verified. All errata have been checked that they get invoked.
