  This example is based on two GD32350R-EVAL-V1.0 boards, it shows I2S0 slave receive
using DMA mode. In this demo, I2S0 is operated as the slave receiver and it will receive 
the data in the i2s0_receive array through I2S0.

  The demo doesn't perform the data transfer actually, which is due to no specific 
master. In the specific application, we must connect another I2S master. if the 
reception process is completed, the data recieved will be print.

  I2S0 CK PIN(PA5)
