Drop old Input workaround

Based on comments from the authors, this should be worked around in
libinput now.

-Subject: [PATCH] Input - synaptics: pin 3 touches when the firmware reports 3
- fingers
-
-Synaptics PS/2 touchpad can send only 2 touches in a report. They can
-detect 4 or 5 and this information is valuable.
-
-In commit 63c4fda (Input: synaptics - allocate 3 slots to keep stability
-in image sensors), we allocate 3 slots, but we still continue to report
-the 2 available fingers. That means that the client sees 2 used slots while
-there is a total of 3 fingers advertised by BTN_TOOL_TRIPLETAP.
-
-For old kernels this is not a problem because max_slots was 2 and libinput/
-xorg-synaptics knew how to deal with that. Now that max_slot is 3, the
-clients ignore BTN_TOOL_TRIPLETAP and count the actual used slots (so 2).
-It then gets confused when receiving the BTN_TOOL_TRIPLETAP and DOUBLETAP
-information, and goes wild.
-
-We can pin the 3 slots until we get a total number of fingers below 2.
