Subject: [PATCH 3/3] clk: mediatek: Use regmap clk-mux for mt8135

The pericfg controller is used by various device drivers, so that it
is implemented via a regmap. In the actual clk implementation for
mt8135, some clk-mux use the traditional register approach which
acceses the register via iomem.
This patch changes the use from iomem to the needed regmap.
