target/arm: Set ID_DFR0.PerfMon for qemu-system-arm -cpu max
We set this for qemu-system-aarch64, but failed to do so for the strictly 32-bit emulation. Fixes: 3bec78447a9 ("target/arm: Provide ARMv8.4-PMU in '-cpu max'") Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Richard Henderson <richard.henderson@linaro.org> Message-id: 20220506180242.216785-8-richard.henderson@linaro.org Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
