powerpc: Fix early boot accounting of CPUs
smp_release_cpus() waits for all cpus (including the bootcpu) due to an off-by-one count on boot_cpu_count (which is all CPUs). This patch replaces that with spinning_secondaries (which is all secondary CPUs). Signed-off-by: Matt Evans <matt@ozlabs.org> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
