memblock: introduce MEMBLOCK_RSRV_NOINIT flag
For reserved memory regions marked with this flag, reserve_bootmem_region
is not called during memmap_init_reserved_pages. This can be used to
avoid struct page initialization for regions which won't need them, for
e.g. hugepages with Hugepage Vmemmap Optimization enabled.
