powerpc/smp: remove the incorrect decrementer initial codes for AP
We already defined start_cpu_decrementer() to invoke decrementer for AP as
the following path:
start_secondary() -> secondary_cpu_time_init() -> start_cpu_decrementer()
So remove these incorrect codes introduced from commit:
e7f75ad0
powerpc/47x: Base ppc476 support
And actually we really should not enable decrementer before calling set_dec().
