Update the Elantech touchpad driver to v5

Could you tell me if issues with pressure reporting mentioned in bugzilla
#8781 have been resolved?

I am not exactly sure what the issue is that is described there.

As far as I know the touchpad does not report pressure (maybe the EeePC
style touchpad does, but I do not have hands on experience with that).
However the Xorg Synaptics driver requires pressure events to work. So I
chose a default pressure value and the driver always toggles between no
pressure and default pressure for no touch and touch respectively. This
seems to work well for all my testers as I have not heard any complaints.

A related issue seems to be that the Ubuntu packaged version of the Xorg
Synaptics driver appears to have a bug where adjusting MaxTapTime doesn't
have any effect. In the absence of true pressure reporting this is the
primary parameter to configure ones personal tapping preference for the
Elantech touchpad. I believe the bug reporter in question wants to set this
value to 0 to disable tapping altogether (although the TouchpadOff option
would be better suited), but because of this bug cannot do so.

So all in all I am not quite sure that this is a problem with the Elantech
driver per se.

I am about to put the driver in my tree and need to know if I can enable
it unconditionally or need to mark it experimental.

Well, either is fine with me. Just getting it in the mainline kernel will
give it a broader exposure and more testing I guess.
