Revert a3a3ed3: "updating 4.19 patches to fix touch and suspend".
Calling intel_ipts_cleanup during suspend causes destroy_doorbell to
fail. Furthermore, removing intel_ipts_cleanup from suspend does not
seem to cause any issues on the Surface Book 1 and 2, and the
introduction of the device link in the previous commit may have fixed
some of the edge-cases/race conditions that may have made this call
necessary in the past. If any issue arises from this, we will deal with
it later in a more subtle way.
See https://github.com/jakeday/linux-surface/issues/544 for an
exhaustive discussion on this.
