Romain Naour 17c516d67a configs/qemu_aarch64_sbsa_defconfig: use ARM cortex a57
Cortex-a53 is not a vaild CPU supported by the SBSA reference machine
[0], so qemu fails to boot in our current defconfig:

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

Use ARM cortex-a57 which is the CPU that SBSA was meant to emulate [1]

Intro
=====
The QEMU sbsa-ref machine is primarily meant for firmware development
and testing according to ARM's SBSA and SBBR standards.
Build
=====
$ make qemu_aarch64_sbsa_defconfig
$ make
Emulation
=========
Run the emulation with:
qemu-system-aarch64 \
-M sbsa-ref \
-cpu cortex-a57 \
-smp 4 \
-m 1024 \
-nographic \
-pflash output/images/SBSA_FLASH0.fd \
-pflash output/images/SBSA_FLASH1.fd \
-hda output/images/disk.img
Note that if you want to run sbsa-ref emulation with QEMU provided by
your distro (i.e., not host-qemu by Buildroot) then you may need to
install the SeaBIOS package for some required drivers. On Debian:
# apt install seabios
