[Jingoo Han]

This patch adds missing device.h header to fix build warnings as below:

drivers/cpuidle/cpuidle.h:26:41: warning: 'struct device' declared inside parameter list [enabled by default]
drivers/cpuidle/cpuidle.h:26:41: warning: its scope is only this definition or declaration, which is probably not what you want
[enabled by default]
drivers/cpuidle/cpuidle.h:27:45: warning: 'struct device' declared inside parameter list [enabled by default]
In file included from drivers/cpuidle/driver.c:15:0:
drivers/cpuidle/cpuidle.h:26:41: warning: 'struct device' declared inside parameter list [enabled by default]
drivers/cpuidle/cpuidle.h:26:41: warning: its scope is only this definition or declaration, which is probably not what you want
[enabled by default]
drivers/cpuidle/cpuidle.h:27:45: warning: 'struct device' declared inside parameter list [enabled by default]
