* Switching VDD_SOC_IN only after PLL2 is turned off. * Weak LDO stabilization delay. * Removed switching to 1.275V before frequency change. * Cleanups in LDO switching. * Removed switching PeriphClk2Div for fCPU <= 24MHz, using AhbDiv instead. * Removed log from _exit that caused logger mutex deadlock
