3fb52e41fd refactor(cpus): remove cpu specific errata funcs
Errata printing is done directly via generic_errata_report.
This commit removes the unused \_cpu\()_errata_report
functions for all cores, and removes errata_func from cpu_ops.

c5c160cddd fix(cpus): flush L2 cache for Cortex-A7/12/15/17
Similar to Cortex-A53, the AArch32-only Cortex-A7/12/15/17 have an
(optional) integrated L2 cache that might need to be flushed if the
whole cluster is powered down. However, unlike Cortex-A53 there is
currently no L2 cache flush in the cluster_pwr_dwn implementation for
some reason. This causes problems if there is unwritten data left in
the L2 cache during a cluster power off.

Fix this by adding the L2 cache flush similar to cortex_a53.S.

bcb3ea92f8 fix(fvp): resolve broken workaround reference
The workaround for CVE 2015-5715 was renamed many years ago, however,
Cortex-A17 and A9 didn't see this change.

e4b34efa18 Workaround for CVE-2017-5715 for Cortex A9, A15 and A17
A per-cpu vbar is installed that implements the workaround by
invalidating the branch target buffer (BTB) directly in the case of A9
and A17 and indirectly by invalidating the icache in the case of A15.

For Cortex A57 and A72 there is currently no workaround implemented
when EL3 is in AArch32 mode so report it as missing.

For other vulnerable CPUs (e.g. Cortex A73 and Cortex A75), there are
no changes since there is currently no upstream AArch32 EL3 support
for these CPUs.
