[PATCH v6 11/54] clk: mediatek: mt8365: Move apmixedsys clock driver to its own file

AngeloGioacchino Del Regno
2023-03-06T14:07:05Z

In preparation for migrating all other mt8365 clocks to the common
mtk_clk_simple_probe(), move apmixedsys clocks to a different file.
While at it, use the builtin_platform_driver() macro for it.

During the conversion, error handling was added to the apmixedsys
probe function.
