Enable legacy 8254 timer on ThinkPad T480 

I also enabled this on T480S, because otherwise SeaBIOS hung.

Enabling it shouldn't cause any harm on the T480, though Mate
did say that his machine seemed to work with my setup.

However, I believe that was when I gave him the ones that lbmk
built with the VGA ROM. Now it builds with libgfxinit, because
Mate was able to fix libgfxinit on this machine.
