* How to setup clock using clock driver functions:
*
* 1. CLOCK_SetSimSafeDivs, to make sure core clock, bus clock, flexbus clock
* and flash clock are in allowed range during clock mode switch.
*
* 2. Call CLOCK_Osc0Init to setup OSC clock, if it is used in target mode.
*
* 3. Set MCG configuration, MCG includes three parts: FLL clock, PLL clock and
* internal reference clock(MCGIRCLK). Follow the steps to setup:
*
* 1). Call CLOCK_BootToXxxMode to set MCG to target mode.
*
* 2). If target mode is FBI/BLPI/PBI mode, the MCGIRCLK has been configured
* correctly. For other modes, need to call CLOCK_SetInternalRefClkConfig
* explicitly to setup MCGIRCLK.
*
* 3). Don't need to configure FLL explicitly, because if target mode is FLL
* mode, then FLL has been configured by the function CLOCK_BootToXxxMode,
* if the target mode is not FLL mode, the FLL is disabled.
*
* 4). If target mode is PEE/PBE/PEI/PBI mode, then the related PLL has been
* setup by CLOCK_BootToXxxMode. In FBE/FBI/FEE/FBE mode, the PLL could
* be enabled independently, call CLOCK_EnablePll0 explicitly in this case.
*
* 4. Call CLOCK_SetSimConfig to set the clock configuration in SIM.
