There are no ibmebus driver that make use of legacy suspend/resume. This
patch removes the support for it from ibmebus framework, new ibmebus driver
(as unlikely as they are) wanting to use suspend/resume should use
dev_pm_ops.

Since there aren't any special bus specific things to do during
suspend/resume and since the PM core will automatically fallback directly
to using the device's PM ops if no bus PM ops are specified there is no
need to have any special ibmebus PM ops at all.

Thanks, this looks like a really nice cleanup.

I don't know the PM code at all, is there any down side to removing all
of this?

cheers
