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.

Make errata reporting mandatory for CPU files

Previously the errata reporting was optional for CPU operation
files and this was achieved by making use of weak reference to

Make errata reporting mandatory for CPU files

Previously the errata reporting was optional for CPU operation
files and this was achieved by making use of weak reference to
resolve to 0 if the symbol is not defined. This is error prone
when adding new CPU operation files and weak references are
problematic when fixing up dynamic relocations. Hence this patch
removes the weak reference and makes it mandatory for the CPU
operation files to define the errata reporting function.
