platform/x86: thinkpad_acpi: Add sysfs control for TrackPoint double-tap
Add a sysfs attribute to enable or disable TrackPoint double-tap hotkey
events at the kernel level.
The TrackPoint firmware enables double-tap support automatically. This
interface allows userspace to control whether double-tap events are
forwarded to userspace.
The attribute is available at:
/sys/devices/platform/thinkpad_acpi/doubletap_enable
0 - Disable double-tap hotkey events
1 - Enable double-tap hotkey events (default)
Filtering is implemented by suppressing ACPI hotkey delivery without
injecting synthetic input events.
