Subject: [PATCH] tile: fix build failure

From: Sudip Mukherjee <sudipm.mukherjee@...il.com>

The build of tilegx allmodconfig was failing with errors like:
../arch/tile/include/asm/div64.h:5:15: error: unknown type name 'u64'
 static inline u64 mul_u32_u32(u32 a, u32 b)
               ^~~
../arch/tile/include/asm/div64.h:5:31: error: unknown type name 'u32'
 static inline u64 mul_u32_u32(u32 a, u32 b)
                               ^~~
../arch/tile/include/asm/div64.h:5:38: error: unknown type name 'u32'
 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]

The simplest solution was to include the types header file.

Fixes: 9e3d6223d209 ("math64, timers: Fix 32bit mul_u64_u32_shr() and friends")
