  This demo is based on the GD32E517Z-EVAL-V1.0 board, it shows how to use the clock
out function of RCU. When program is running, user could press the key d to select
different clock source to output. Demo has six clock source, once the key is pressed,
the source will change and the corresponding led will light on. Debug information can
be printed from COM0 by using USART0. The clock output pin is PA8.
