Input: synaptics - fix regression with "image sensor" trackpads
commit 7968a5dd492ccc38345013e534ad4c8d6eb60ed1
Input: synaptics - add support for Relative mode
Accidentally broke support for advanced gestures (multitouch)
on some trackpads such as the one in my ThinkPad X220 by
incorretly changing the condition for enabling them. This
restores it.
