For 5.8, we are going to make iptsd the default, which mostly supports
4.19 level multitouch, instead of just singletouch + stylus.
This replaces the old ipts driver with the new UAPI version that is
required for iptsd.

On the Pro 7 and Laptop 3, intel_lpss_pci fails to probe and thus keeps

Note: The added patch is on it's way upstream.
See: https://lkml.org/lkml/2019/10/16/1230
This commit will update suspend.patch for 4.19
Backported these two patches:

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.
The newer surface devices Pro 4 and up do not define _PRW to specify
which GPE interrupt belongs to the lid. Thus they may not be marked as
wake-up sources automatically, so we have to do this manually.
This patch ensures that a GPIO driver is loaded and set up before the
button driver can bind to the MSHW0040 device. Without this the driver
may not bind to the MSHW0040 device at all.
Adds a driver for the Surface platform Integration Device (SID) of the
Surface Book 2. This allows for setting the performance-mode, which can
be used to choose between performance-optimized vs. quiet operation.
The performance-mode can be set via the perf_mode sysfs attribute on the
corresponding device (MSHW0107).
