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.
