Changes:
surface3-spi:
- Dropped this patch in favor of the surface3-touchscreen-dma-fix
patch (which is taken from the upstream DMA fix). For details, take
a look at the commit history of kernel repo linked below.
surface3-touchscreen-dma-fix:
- Added this patch as a successor to the dropped surface3-spi patch.
For details, take a look at the commit history of kernel repo linked
below.
Note: currently, this patch is available upstream only on v5.8,
v5.7, and v5.4 and not backported to any older LTS kernels. So,
this patch was backported from upstream commit ourselves.

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.
