This patch introduces the generic numa_memblks for LoongArch. In detail: 1. Enable NUMA_MEMBLKS (but disable NUMA_EMU) in Kconfig; 2. Use generic definition for numa_memblk and numa_meminfo; 3. Use generic implementation for numa_add_memblk() and its friends; 4. Use generic implementation for numa_set_distance() and its friends; 5. Use generic implementation for memory_add_physaddr_to_nid() and its friends. Note: Disable NUMA_EMU because it needs more efforts and no obvious demand now.

SPARSEMEM_VMEMMAP uses a virtually mapped memmap to optimise pfn_to_page and page_to_pfn operations. This is the most efficient option when sufficient kernel resources are available.
