powerpc/44x: Mark mmu_init_secondary() as __init

mmu_init_secondary() calls ppc44x_pin_tlb() which is marked __init,
leading to a warning:

  The function mmu_init_secondary() references
  the function __init ppc44x_pin_tlb().

There's no CPU hotplug support on 44x so mmu_init_secondary() will
only be called at boot. Therefore we should mark it as __init.
