watchdog: Intel SCU Watchdog: Fix build and remove duplicate code

Trying to build the Intel SCU Watchdog fails for me with gcc 4.6.0 -
$ gcc --version | head -n 1
gcc (GCC) 4.6.0 20110513 (prerelease)

like this :
  CC      drivers/watchdog/intel_scu_watchdog.o
In file included from drivers/watchdog/intel_scu_watchdog.c:49:0:

cc1: some warnings being treated as errors

make[1]: *** [drivers/watchdog/intel_scu_watchdog.o] Error 1
make: *** [drivers/watchdog/intel_scu_watchdog.o] Error 2

Additionally, linux/types.h is needlessly being included twice in 
drivers/watchdog/intel_scu_watchdog.c
