Unify cpu_init for all Kinetis CPUs to reduce code duplication. Updated the MCG driver implementation to make the configuration easier. Most clock settings are initialized by kinetis_mcg_init() called from cpu_init. Board specific external clock source initialization (FRDM-K64F, PhyNode) needs to be performed in board_init instead of in cpu_init.
