The firmware knows how many hot keys it supports, so export this
information in a sysfs attribute.
And the driver knows which keys are always handled by the firmware in all
known ThinkPad models too, so export this information as well in a sysfs
attribute. Unless you know which events need to be handled in a passive
way, do *not* enable hotkeys that are always handled by the firmware.
