Set ->init_time() to NULL to use the default ARM behaviour which happens to be clocksource_of_init(). Also, replace the call to shmobile_time_init() with clocksource_of_init(). Finally, remove shmobile_init_time() that now is unused.

Set ->init_time() to NULL to use the default ARM behaviour which happens to be clocksource_of_init(). Also, replace the call to shmobile_time_init() with clocksource_of_init(). Finally, remove shmobile_init_time() that now is unused.

Thanks, I will queue these up for v3.12 in the cleanup3 branch.
