ACPI: thinkpad-acpi: export hotkey maximum masks
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.
