[PATCH] cpuidle: Default y for pseries

We just replaced the pseries platform idle loops with a cpuidle backend,
however that means that you won't get any power saving and won't return
any unused idle time to the hypervisor unless cpuidle is enabled.
Thus is should default to y when pseries is enabled. I prefer that to
a select so we can still make it modular if we want to.

Linus, do you want to just pick that up or should I put it into powerpc.git
and ask you to pull ? I will have 2 or 3 other fixes there later today,
but I wanted to make sure you were ok with the approach with this
