[PATCH v1 08/45] clk: mediatek: mt2712: Move apmixedsys clock driver to its own file

AngeloGioacchino Del Regno
2023-02-06T15:30:29Z

The only clock driver that does not support mtk_clk_simple_probe() is
apmixedsys: in preparation for enabling module build of non-critical
mt2712 clocks, move this to its own file.
While at it, also fix some indentation issues in the PLLs table.
