platform/x86: thinkpad_acpi: Support for trackpoint doubletap
Lenovo trackpoints are adding the ability to generate a doubletap event.
This handles the doubletap event and sends the KEY_PROG4 event to
userspace. Despite the driver itself not using KEY_PROG1 - KEY_PROG3 this
still uses KEY_PROG4 because of some keys being remapped to KEY_PROG1 -
KEY_PROG3 by default by the upstream udev hwdb containing:
evdev:name:ThinkPad Extra Buttons:dmi:bvn*:bvr*:bd*:svnLENOVO*:pn*:*
...
KEYBOARD_KEY_17=prog1
KEYBOARD_KEY_1a=f20 # Microphone mute button
KEYBOARD_KEY_45=bookmarks
KEYBOARD_KEY_46=prog2 # Fn + PrtSc, on Windows: Snipping tool
KEYBOARD_KEY_4a=prog3 # Fn + Right shift, on Windows: No idea
