We can assign and verify the address before realizing and trying to plug. reading/writing the address property should never fail for DIMMs, so let's reduce error handling a bit by using &error_abort. Getting access to the memory region now might however fail. So forward errors from get_memory_region() properly. As all memory devices should use the alignment of the underlying memory region for guest physical address asignment, do detection of the alignment in pc_dimm_pre_plug(), but allow pc.c to overwrite the alignment for compatibility handling.
