powerpc: Silence __cpu_up() under normal operation

During CPU offline/online tests __cpu_up would flood the logs with
the following message:

Processor 0 found.

This provides no useful information to the user as there is no context
provided, and since the operation was a success (to this point) it is expected
that the CPU will come back online, providing all the feedback necessary.

Change the "Processor found" message to DBG() similar to other such messages in
the same function. Also, add an appropriate log level for the "Processor is
stuck" message.
