clk: mediatek: add missing cpu mux causing Mediatek cpufreq can't work This patch adds CPU multiplexer clocks which are essential for Mediatek cpufreq driver. It would use the CPU clock multiplexer to switch to the intermediate clock source temporarily and then wait for the primary clock changing getting stable.
