Subject: [PATCH] INPUT: Give more precise auto repeat control for gpio_keys driver

gpio_keys_platform_data has a rep flag to control auto repeat feature. But
It is not enough, for example, there is a situation that most of buttons are repeatable, while some buttons like poweroff or mute can't be repeatable. By adding another repeat flag for gpio_keys_button, we could precisely control that.
