clk: mediatek: mt8167: Convert to mtk_clk_simple_{probe,remove}()

Convert topckgen and infracfg clock drivers to use the common
mtk_clk_simple_probe() mechanism and change this from the old
"static" CLK_OF_DECLARE to be a platform driver, allowing it
to eventually be built as a module.

Thanks to the conversion, more error handling was added to the clocks
registration.
