 input: trackpoint - Enable doubletap by default on capable devices 
Enable doubletap functionality by default on TrackPoint devices that
support it. The feature is detected using firmware ID pattern matching
(PNP: LEN03xxx) with a deny list of incompatible devices.

This provides immediate doubletap functionality without requiring
userspace configuration. The hardware is enabled during device
detection, while event filtering continues to be handled by the
thinkpad_acpi driver as before.
