powerpc: Replace cpu_up/down() with add/remove_cpu()
The core device API performs extra housekeeping bits that are missing from directly calling cpu_up/down. See commit a6717c01ddc2 ("powerpc/rtas: use device model APIs and serialization during LPM") for an example description of what might go wrong. This also prepares to make cpu_up/down() a private interface of the CPU subsystem.
