platform/surface: Add OF support

Add basic support for registering the aggregator module on Device Tree-
based platforms. These include at least three generations of Qualcomm
Snapdragon-based Surface devices:

- SC8180X / SQ1 / SQ2: Pro X,
- SC8280XP / SQ3: Devkit 2023, Pro 9
- X Elite: Laptop 7 / Pro11

Thankfully, the aggregators on these seem to be configured in an
identical way, which allows for using these settings as defaults and
no DT properties need to be introduced (until that changes, anyway).

Based on the work done by Maximilian Luz, largely rewritten.
