Dear Krzysztof,

There are two reasons for adding a new compatible string to MT8189:
On the one hand, MT8189 is a pure single-core hardware chip, so the
of_device_id data is different;
On the other hand, the correct chip name can be set through the
compatible strings;
The above two reasons are reflected in the following patch:

Thanks.
