cpu: Correctly call parent on switchOut() and takeOverFrom()
This patch cleans up the CPU switching functionality by making sure
that CPU models consistently call the parent on switchOut() and
takeOverFrom(). This has the following implications that might alter
current functionality:
* The call to BaseCPU::switchout() in the O3 CPU is moved from
signalDrained() (!) to switchOut().
* A call to BaseSimpleCPU::switchOut() is introduced in the simple
CPUs.
