Subject: [PATCH 3/5] platform/surface: aggregator_registry: Add support for Surface Laptop Studio 2

Add SAM client device nodes for the Surface Laptop Studio 2 (SLS2). The
SLS2 is quite similar to the SLS1, but it does not provide the touchpad
as a SAM-HID device. Therefore, add a new node group for the SLS2 and
update the comments accordingly. In addition, it uses the new fan
control interface.
