[Buildroot] [PATCH 7/8] arch/Config.in.arm: Add Cortex-A53 CPU

[Yann E. MORIN]

From: Matt Flax <flatmax at flatmax.org>

Adds the Cortex-A53 CPU to the target architecture variant choice. This
sets the toolchain to use Cortex-A53 as the target. The effect is that
various Cortex-A53 tunings are enabled for the compilation of packages.
