s390/zcrypt: Convert to PM ops
Switch the zcrypt bus from legacy suspend/resume callbacks to dev_pm_ops.
The conversion is straight forward with the help of SIMPLE_DEV_PM_OPS().
The new dev_pm_ops based version is functionally equivalent to the legacy
callbacks version.
This will allow to eventually remove support for legacy suspend/resume
callbacks from the kernel altogether.
