32-bit ARM max CPU is a 'Cortex-A57 advertising none of the AArch64
features'. Keep it as close as possible as the A57, by implementing
the debug ID registers, following the changes in aarch64_a57_initfn
added by commits 48eb3ae64b3 ("target-arm: Adjust debug ID registers
per-CPU") and 09754ca867f ("target/arm: Implement AArch32 DBGDEVID,
DBGDEVID1, DBGDEVID2").
