[PATCH 21/32] clk: mediatek: mt7986-apmixed: Switch to common probe/remove helpers

The MT7986 apmixed 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.
