Actually, someone else has already found the correct values for the T440p.
https://github.com/leoluk/thinkpad-stuff/wiki/Haswell-ThinkPad-problems#linux-docking-station-audio-compatibility

I have modified the values to fit the T440s:
File: /lib/firmware/hda-jack-retask.fw
--------------------------------------
[codec]
0x10ec0292 0x17aa220c 0

[pincfg]
0x16 0x2121101f
0x19 0x21a11030
--------------------------------------
I tested the settings and can confirm that docking headphone + mic works 
correctly, but I am not sure what these values do/mean exactly.

Possibly they need to be corrected...
