ARM / mach-shmobile: r8a7779 SMP TWD boot regression fix
Fix SMP TWD boot regression on r8a7779 based platforms caused by: 4200b16d ARM: shmobile: convert to twd_local_timer_register() interface After the merge of the above commit it has been impossible to boot r8a7779 based SoCs with SMP enabled and CONFIG_HAVE_ARM_TWD=y. The kernel crashes at smp_init_cpus() timing which is before the console has been initialized, so to the user this looks like a kernel lock up without any particular error message. This patch fixes the regression on r8a7779 by moving the TWD registration code from smp_init_cpus() to sys_timer->init() time.
