Adolfo Delorenzo 65938d6d04 fix(qemu): use -cpu max so piCore64 binaries don't hit instruction aborts ...

piCore64's BusyBox segfaults under QEMU virt with -cpu cortex-a72, generating
an EL0 Instruction Abort (el0_ia in the panic call trace). The binary is built
with ARMv8 extensions (likely +lse atomics, +crypto, or +fp16) that the
cortex-a72 model doesn't enable by default.

Switch to -cpu max which enables all emulated ARMv8 features. This is fine for
dev testing; the actual production hosts (Graviton, Ampere, real ARM64
hardware) all have these features natively.
