Modularize evdev

Browse Source 
- Convert "options EVDEV" to "device evdev" and "device uinput", add
    modules for both new devices. They are isolated subsystems and do not
    require any compile-time changes to general kernel subsytems
- For hybrid drivers that have evdev as an optional way to deliver input
    events add option EVDEV_SUPPORT. Update all existing hybrid drivers
    to use it instead of EVDEV
- Remove no-op DECLARE_MODULE in evdev, it's not required, MODULE_VERSION
    is enough
- Add evdev module dependency to uinput
