memory-device: complete factoring out pre_plug handling

Browse source 
With all required memory device class functions in place, we can factor
out pre_plug handling of memory devices. Take proper care of errors. We
still have to carry along legacy_align required for pc compatibility
handling.

We will factor out tracing of the address separately in a follow-up
patch.
