* Name: nrf52_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 nrf52_serialinit. NOTE: This function depends on GPIO pin
* configuration performed in xmc_lowsetup() and main clock initialization
* performed in xmc_clock_configure().
*
