Reduce the slot count where the touchpad has more slots than it supports
Where a touchpad sends BTN_TOOL_foo
for any foo > active slot count
, we assume that the touchpad is lying about it's actually supported number of slots and drop the number of slots down to whatever we actually have.
Fixes #408 (closed)
This does not currently pass the test suite because the device has weird dimensions, see #408 (comment 381318). Depending on whether this gets fixed in the 60-evdev.hwdb we may not need to adjust the test cases.
