s390/zcrypt: fix suspend/resume of AP bus devices If there are no devices on the AP bus there will not be a single call to the per-device ap_bus_suspend function. Even worse, there will not be a call to the per-device ap_bus_resume either and the AP will fail so resume correctly. Introduce a bus specific dev_pm_ops to suspend / resume the AP bus related things. While we are at it, simplify the power management code of the AP bus.
