ARM: shmobile: r8a7779: Stop powering down secondary CPUs during early boot
At .smp_prepare_cpus() time, CPUs 1-3 are still powered down:
- The bootloader doesn't enable CPUs 1-3,
- Non-boot CPUs are disabled by kexec before starting the new kernel.
Hence there is no need to try to power them down again, as it will fail
silently with -EIO anyway.
