Commit Message

AngeloGioacchino Del Regno Feb. 21, 2023, 11:55 a.m. UTC 
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.
