refactor(cpus): directly invoke errata reporter

In all non-trivial cases the CPU specific errata functions
already call generic_errata_report, this cuts out the middleman
by directly calling generic_errata_report from
print_errata_status.

The CPU specific errata functions (cpu_ops->errata_func)
can now be removed from all cores, and this field can be
removed from cpu_ops.

Also removes the now unused old errata reporting
function and macros.
