AngeloGioacchino Del Regno Feb. 6, 2023, 3:29 p.m. UTC 
In preparation for migrating all other mt8183 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 and fix
some indentation issues in the PLLs table.
