On the Pro 7 and Laptop 3, intel_lpss_pci fails to probe and thus keeps
the system from booting. Add a patch to fix this.
Note: The added patch is on it's way upstream.
See: https://lkml.org/lkml/2019/10/16/1230
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.
