Some buttons are mapped to higher button numbers. For example, BTN_0 is
posted as button 8 if BTN_LEFT is present. On top of that, the
driver-specific button mapping may map the button to something else again.
We need to take these mappings into account when counting the number of
buttons on the device.
Example: A device with BTN_LEFT and BTN_0 and a mapping from 1 -> 7 and 8 ->
2.
BTN_LEFT is mapped to 1. 1 is mapped to 7. num_buttons is 7.
BTN_0 is mapped to 8. 8 is mapped to 2. num_buttons remains 7.
