Subject[PATCH v3 10/15] parisc: 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

This also prepares to make cpu_up/down a private interface for anything
but the cpu subsystem.

Helge, this now uses add_cpu() which you should be CCed on. I wasn't sure if
I can keep your Ack or remove it in this case. Please let me know if you need
more clarification.
