Modify the gpio_keys support in x86_android_tablet_init() for tablets which have more then 1 key/button which needs to be handled by the gpio_keys driver. This requires copying over the struct gpio_keys_button from the x86_gpio_button struct array to a new gpio_keys_button struct array, as an added benefit this allows marking the per model x86_gpio_button arrays __initconst so that they all can be freed after module init().
