[PATCH 1/3] clk: mediatek: clk-mtk: Add cpumux support to common probe/remove helpers

[Akari Tsuyukusa]

Extend __mtk_clk_simple_probe() and __mtk_clk_simple_remove() to support
cpumux clocks. This reduces boilerplate code in drivers for SoCs that
require cpumux registration, such as mt6795-infracfg.
