math64, tile: Fix build failure

The build of tilegx allmodconfig fails with:
../arch/tile/include/asm/div64.h:5:15: error: unknown type name 'u64'
 static inline u64 mul_u32_u32(u32 a, u32 b)
               ^~~

In file included from ../fs/ubifs/ubifs.h:26:0,
                 from ../fs/ubifs/shrinker.c:42:
../include/linux/math64.h: In function 'mul_u64_u32_shr':
../arch/tile/include/asm/div64.h:9:21: error: implicit declaration of
	function 'mul_u32_u32' [-Werror=implicit-function-declaration]

Include the linux/types.h in tiles div64.h to slve the problem.
