clk: mediatek: mt2701-vdec: fix conversion to mtk_clk_simple_probe

Commit 973d160 ("clk: mediatek: mt2701: use mtk_clk_simple_probe to
simplify driver") broke DT bindings as the highest index was reduced by
1 because the id count starts from 1 and not from 0.

Fix this, like for other drivers which had the same issue, by adding a
dummy clk at index 0.
