[PATCH v1 0/5] rust: Add ACPI match table support for Rust drivers

[Igor Korotin <igor.korotin.linux@gmail.com>]

This patch series introduces support for ACPI match tables in Rust 
drivers.

Currently, Rust abstractions support only Open Firmware (OF) device 
matching. This series extends the driver model to support ACPI-based 
matching, enabling Rust drivers to bind to ACPI-described devices.

Changes include:
  - A new `acpi::DeviceId` abstraction for working with 
   `struct acpi_device_id`.
  - A helper function `is_of_node()` for determining fwnode types.
  - Updates to the core `Adapter` trait and `platform::Driver` to support
    optional ACPI ID tables.
  - A sample implementation in the Rust platform driver, demonstrating 
    multi-bus matching.

This is especially useful for writing drivers that work across platforms 
using both OF and ACPI.

Tested using QEMU with a custom SSDT that creates an ACPI device matching
the sample Rust platform driver.
