quirks: extend/restore the Elan Touchpads quirks

The hwdb match entry used to be this one:
 libinput:name:*Elan Touchpad*:dt:*
  LIBINPUT_ATTR_PRESSURE_RANGE=10:8
from commit 596777a. It was intended to match
for devicetree only but the way the udev rules were composed, it ended up
matching on any system.

Restore that for all systems to have compatibility with 1.11. For this one,
let's also add the resolution hint and hope that that works too.

Fixes #140
