For I2C devices described via ACPI the i2c_board_info.type string is set to the ACPI device name. When using ACPI and DT ids this string ends up something like "PRP0001:00". If the of_compatible property is present try to use that instead. This makes it easier to instantiate i2c drivers through ACPI with DT ids.
