platform/x86: thinkpad_acpi: Add support for new phone link hotkey

The F11 key on the new Lenovo Thinkpad T14 Gen 5, T16 Gen 3, and P14s
Gen 5 laptops includes a symbol showing a smartphone and a laptop
chained together.  According to the user manual, it starts the Microsoft
Phone Link software used to connect to Android/iOS devices and relay
messages/calls or sync data.

These laptops send the 0x1320 hkey event when the key is pressed.  Map
this event to the new KEY_LINK_PHONE keycode.
