    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.
