 * Name: kinetis_earlyserialinit
 *
 * Description:
 *   Performs the low level UART and LPUART initialization early in debug
 *   so that the serial console will be available during bootup.  This must
 *   be called before up_serialinit.  NOTE:  This function depends on GPIO
 *   pin configuration performed in up_consoleinit() and main clock
 *   initialization performed in up_clkinitialize().
