The Mediatek clk driver library handles duplicate clock IDs in two
different ways: either ignoring the duplicate entry, or overwriting
the old clk. Either way may cause unexpected behavior, and the latter
also causes an orphan clk that cannot be cleaned up.
Align the behavior so that later duplicate entries are ignored, and
a warning printed. The warning will also aid in making the issue
noticeable.
