arch_init: align MR size to target page size
Migration code assumes that each MR is a multiple of TARGET_PAGE_SIZE: MR size is divided by TARGET_PAGE_SIZE, so if it isn't migration never completes. But this isn't really required for regions set up with memory_region_init_ram, since that calls qemu_ram_alloc which aligns size up using TARGET_PAGE_ALIGN. Align MR size up to full target page sizes, this way migration completes even if we create a RAM MR which is not a full target page size. Signed-off-by: Michael S.
