[PATCH v1 0/4] revert latest PPC64 NVDIMM changes

Hi, In [1], Daniel pointed out that the changes made by [2] are uncompliant with the Libvirt design of not doing anything that can compromise guests in the wild. This series aims to solve that by reverting the changes made by [2]. It also enhances the auto-alignment of ppc64 NVDIMM in a way that we can have consistency between the sizes reported in the domain XML and what QEMU will see, while not hurting any running guests that are already using the auto-alignment feature. For simplicity, first patch contains the revert of all relevant patches from [2] in a single commit.
