Round up RAMBlock sizes to host page sizes
RAMBlocks that are not a multiple of host pages in length
cause problems for postcopy (I've seen an ACPI table on aarch64
be 5k in length - i.e. 5x target-page), so round RAMBlock sizes
up to a host-page.
This potentially breaks migration compatibility due to changes
in RAMBlock sizes; however:
1) x86 and s390 I think always have host=target page size
2) When I've tried on Power the block sizes already seem aligned.
3) I don't think there's anything else that maintains per-version
machine-types for compatibility.
