It needs different firmware from the factory, so we need to distinguish
it from software in order to be able to update it correctly.

Let the keyboard figure out by itself whether the system is asleep by
looking at the USB connection state.
| | USB Active | USB Suspend |
| Lid Open | LED, keys | No LED, keys |
| Lid closed | No LED, no keys | No LED, no keys |
=> lid_open => keys registered
=> lid_open && !suspended => LEDs on
After waking from sleep, backlight does not turn back on.
Remove the custom backlight/sleep logic. Don't try to outsmart the core
quantum logic, let it handle the hard stuff. Our code just
suspends/wakes the keyboard.
