I just want to say the hot-keys on keyboard for brightness, sound
volume, display output switching won't change too much, 
because user needs these buttons. And almost all laptops implement them.

For each ODM, if they implement hot-keys with dedicated ACPI devices and
dedicated AML methods. It doesn't make any sense to change
the name on new platforms for supporting same hot-keys.

We need a hotkey spec for those well-know hot-keys now,
Then, we can look forward to a clean hotkey driver in the future.
