powerpc: Don't idle with the wait instruction on booke

It appears idling via 'wait' on e5500 causes strange behaviors, such as
top(1) simply hanging sporadically, until input.  Until this can possibly be
sorted out (interrupt issue?), just don't idle on this hardware.  The SoCs
are low power already, and the wait state doesn't save much anyway.
