[PATCH 24/32] clk: mediatek: mt8167-apmixedsys: Switch to common probe/remove helpers

[Akari Tsuyukusa <akkun11.open@gmail.com>]

The MT8167 apmixedsys driver can use the MediaTek clock framework
common initialization sequence. Reduce boilerplate code by creating
struct mtk_clk_desc and using the mtk_clk_simple_probe/remove helpers.
Also, add a remove callback to properly support module unloading.
