powerpc/e500mc: Add support for the wait instruction in e500_idle
e500mc cannot doze or nap due to an erratum (as well as having a
different mechanism than previous e500), but it has a "wait" instruction
that is similar to doze.
On 64-bit, due to the soft-irq-disable mechanism, the existing
book3e_idle should be used instead.
