qemu/aarch64-virt: Emulate cortex-a53 in qemu to match Buildroot config

Browse source 
qemu_aarch64_virt_defconfig (implicitly) specifies cortex-a53, so adjust the
QEMU command line to also emulate a a53 instead of a57.

Also adjust the defconfig to explicitly specify a53 for consistency/clarity.

Run the emulation with:
qemu-system-aarch64 -M virt -cpu cortex-a57 -nographic -smp 1 -kernel output/images/Image -append "root=/dev/vda console=ttyAMA0" -netdev user,id=eth0 -device virtio-net-device,netdev=eth0 -drive file=output/images/rootfs.ext4,if=none,format=raw,id=hd0 -device virtio-blk-device,drive=hd0
