clk: mediatek: mt8167: Move apmixedsys as platform_driver in new file
In preparation for migrating all other MT8167 clocks to the common
mtk_clk_simple_probe(), move apmixedsys clocks to a different file.
While at it, also migrate away from the legacy CLK_OF_DECLARE and
convert this clock driver to be a platform_driver instead.
During the conversion, error handling was added to the apmixedsys
probe function.
