 * Name: nrf91_earlyserialinit
 *
 * Description:
 *   Performs the low level UART initialization early in debug so that the
 *   serial console will be available during bootup.  This must be called
 *   before nrf91_serialinit.  NOTE:  This function depends on GPIO pin
 *   configuration performed in xmc_lowsetup() and main clock initialization
 *   performed in xmc_clock_configure().
