[Buildroot] [PATCH 1/2] configs/qemu_aarch64_sbsa_defconfig: use ARM cortex a57

[Romain Naour]

When booting with cortex-a53, qemu refuse to start with the following message [1]:

  qemu-system-aarch64: sbsa-ref: CPU type other than the built-in cortex-a57 not supported

Use ARM cortex a57 as requested by Qemu.
