ARM / mach-shmobile: r8a7779 SMP TWD boot regression fix
Fix SMP TWD boot regression on r8a7779 based platforms caused by:
4200b16 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.
