[PATCH] sh: kernel: cpu: provide 'NULL' parameter for calling cpuidle_register().

[Chen Gang <gang.chen@asianux.com>]

Need provide additional parameter for calling cpuidle_register() just
like some of another architectures have done, or can not pass compiling.

The related error (with kfr2r09_defconfig):

    CC      arch/sh/kernel/cpu/shmobile/cpuidle.o
  arch/sh/kernel/cpu/shmobile/cpuidle.c: In function 'sh_mobile_setup_cpuidle':
  arch/sh/kernel/cpu/shmobile/cpuidle.c:102:2: error: too few arguments to function 'cpuidle_register'
    return cpuidle_register(&cpuidle_driver);
