From: Dmitry Vyukov <dvyukov@google.com>

Including sparsemem.h from other files (e.g. transitively via
asm/pgtable_64_types.h) results in compilation errors due to unknown
types:

sparsemem.h:34:32: error: unknown type name 'phys_addr_t'
extern int phys_to_target_node(phys_addr_t start);
                               ^
sparsemem.h:36:39: error: unknown type name 'u64'
extern int memory_add_physaddr_to_nid(u64 start);
                                      ^

Fix these errors by including linux/types.h from sparsemem.h
This is required for the upcoming KMSAN patches.
