libnvdimm, pmem: Change pmem physical sector size to PAGE_SIZE

Based on a patch: c8fa317 brd: Request from fdisk 4k alignment by Boaz
Harrosh, allow fdisk to create properly aligned partitions for DAX. This
will also cause mkfs.ext4 to emit a warning if using a file system block
size of less than PAGE_SIZE.
