[PATCH 5/7] clk: mediatek: mt6797: use mtk_clk_simple_probe to simplify driver

From: Miles Chen
Date: Thu Sep 22 2022 - 05:19:39 EST


mtk_clk_simple_probe was added by Chun-Jie to simply common flow
of MediaTek clock drivers and ChenYu enhanced the error path of
mtk_clk_simple_probe and added mtk_clk_simple_remove.

Let's use mtk_clk_simple_probe and mtk_clk_simple_probe in other
MediaTek clock drivers as well.
