Fix elantech touchpad after suspend/resume

Hi guys,

this is an attempt to fix problem os Asus laptops which touchpads
stop to work after a suspend/resume. It's kind of a big hammer, but I couldn't
find any other way to do it.

As described in the first patch, when i8042 controller receives a selftest in some
models of elantech touchpads, the elantech driver fails to detect the device.

Is there any other alternative to fix this problem in a more elegant way?

Thanks,
