2025 Thinkpads F11 key launch the Intel Unison app on Windows,
which does some sort of smart sharing between laptop and phone.

Map this key event to KEY_LINK_PHONE as the closest thing we have.
This prevents an error message being displayed on key press.

Thank you for your contribution, it has been applied to my local
review-ilpo-fixes branch. Note it will show up in the public
platform-drivers-x86/review-ilpo-fixes branch only once I've pushed my
local branch there, which might take a while.

The list of commits applied:
