iommu/mediatek: Use component_match_add

In order to simplify the error patch(avoid call of_node_put), Use
component_match_add instead component_match_add_release since we are only
interested in the "device" here. Then we could always call of_node_put in
normal path.

Strictly this is not a fixes patch, but it is a prepare for adding the
error path, thus I add a Fixes tag too.
