Subject[PATCH v4 19/54] clk: mediatek: mt8183: Move apmixedsys clock driver to its own file
Date
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.

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