Export `acpi_of_match_device` function and use it to match the of device
table against ACPI PRP0001 in Rust.
This fixes id_info being None on ACPI PRP0001 devices.
Using `device_get_match_data` is not possible, because Rust stores an
index in the of device id instead of a data pointer. This was done this
way to provide a convenient and obvious API for drivers, which can be
evaluated in const context without the use of any unstable language
features.
Fixes: 7a718a1f26 ("rust: driver: implement `Adapter`")
