  This demo is based on the GD32F30x-EVAL board, it shows the I2C programming 
mode in master receiving mode. In this demo,I2C0 is operated as master receiver,
and the SCL line and SDA line of I2C0 interface are controled by the I/O pin 
PB6 and PB7 respectively.
  This demo shows the receiving data process of the master. And it will store 
the received data in the i2c_receiver array.
  This demo doesn't perform the data transfer actually, which is due to no 
specific slave.In the specific application, we must send the correct slave 
address, and the master and the slave may need to be connected by the jumper 
if necessary. When the macro I2C_10BIT_ADDRESS is 1, I2C communicate in 10 bit
addressing mode, otherwise, I2C communicate in 7 bit addressing mode.
