[PATCH synaptics] Remove absolute mode

[Peter Hutterer]

Moving a touchpad in absolute mode is unusual - touchpads are disconnected
from the output device, so direct interaction is hard. There appears to be
little usage of it (I haven't seen bug reports from people claiming to use
it). Joe Shaw, author of the code and only known user doesn't have a use for
it anymore, so purge it from the repo.
