Revert "hwdb: add a touchpad hwdb"

The main purpose of this hwdb was to tag touchpads that have the physical
trackstick buttons wired to the touchpad (Lenovo Carbon X1 3rd, Lenovo *50
series).  This hwdb is not required on kernels 4.0 and above, the kernel now
re-routes button presses through the trackstick's device node. Userspace does
not need to do anything.

See kernel commit cdd9dc195916ef5644cfac079094c3c1d1616e4c.

This reverts commit 001a247324b44c0e0b8fdba41a6fc66e7465b8b6.

-# This file is part of systemd.

-# The lookup keys are composed in:
-#   70-touchpad.rules
-#
-# Note: The format of the "touchpad:" prefix match key is a
-# contract between the rules file and the hardware data, it might
-# change in later revisions to support more or better matches, it
-# is not necessarily expected to be a stable ABI.
-#
-# Match string format:
-# touchpad:pnpid:<pnpid>:
-#
-# To add local entries, create a new file
-#   /etc/udev/hwdb.d/71-touchpad-local.hwdb
-# and add your rules there. To load the new rules execute (as root):
-#   udevadm hwdb --update
-#   udevadm trigger /dev/input/eventXX
-# where /dev/input/eventXX is the touchpad in question. If in
-# doubt, simply use /dev/input/event* to reload all input rules.
-#
-# If your changes are generally applicable, open a bug report on
-#   http://bugs.freedesktop.org/enter_bug.cgi?product=systemd
-# and include your new rules, a description of the device, and the
-# output of
-#   udevadm info /dev/input/eventXX
-# (or /dev/input/event*).
-#
-# Allowed properties are:
-#    TOUCHPAD_HAS_TRACKPOINT_BUTTONS=1
-#
-# If the TOUCHPAD_HAS_TRACKPOINT_BUTTONS property is set, this
-# device has # the trackpoint buttons wired up to the touchpad as
-# BTN_0, BTN_1 and BTN_2. This affects the Lenovo X1 Carbon 3rd
