eeepc-laptop: make input device a child of the platform device
Sysfs showed the ehotk input device as a "virtual" device - lies!
The input device is provided by a physical device, the eeepc platform.
This requires that we move the creation of the input device to come
after platform device is created. Input initialization is moved from
ehotk_check() [sic] to a new function called eeepc_input_init(). This
brings the input device into line with the other eeepc-laptop devices.
Also, refuse to load if we fail to register the input device.
