Subject: [PATCH 3/3] platform/surface: aggregator_registry: Add HID devices for sensors and UCSI client to SP8

Add software nodes for the HID sensor collection and the UCM UCSI HID
client to the Surface Pro 8. In contrast to the type-cover devices,
these devices are directly attached to the SAM controller, without any
hub.

This enables support for HID-based sensors, including the ones used for
automatic screen rotation, on the Surface Pro 8.
