ARM: mach-shmobile: sh73a0 twd_base fix
Fix the case of too late twd_base initialization for SMP
on sh73a0 which bas been broken because sh73a0 specific
smp_prepare_cpu() and percpu_timer_setup() changed order
in the commits:
05c74a6cbcfb416286a947668ba32f63d99fe74a
c413521eb4e2d7ffd5ce432a144708d479054bd3
Without this fix the sh73a0 SMP kernel panics on boot.
