Series rust: Add ACPI match table support for Rust drivers | expand

Commit Message

Igor Korotin June 5, 2025, 4:24 p.m. UTC 
Add a helper function to determine whether a given device appears to be
an Open Firmware (OF) node.

This function will be used in Rust driver abstractions to support both
ACPI and OF matching simultaneously in subsequent patches.
