rust: ACPI: fix missing match data for PRP0001

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.
