Sony DualShock 4: disable drumroll suppression

After further investigation, it seems that while disabling drumroll
detection by speed change fixed pointer movement issues, the bad pointer
speed values were also breaking tap-to-click. I can't produce drumroll
issues on this touchpad anyway, so let's just disable drumroll
suppression completely.

Bug: 329585708
Test: connect DualShock 4 by Bluetooth, check tapping to click works,
      drum your fingers on the pad and check the cursor doesn't jump
      around
