The A53 is an ARM64 CPU, so it should rather be added to
Config.in.aarch64 (in which we don't yet have a CPU selection, but that
can be added).

Or are you building a 32 bits ARM system for a Cortex-A53 ? In that
case, adding it to Config.in.arm would be OK, but it's a bit annoying
that we would have to duplicate many ARM CPUs between Config.in.arm and
Config.in.aarch64.
