Implement the functions of I2C host and target.
I2CM: supports nine hosts and each one able located at I2C interface
0~12.
supports two 32 bytes dedicated FIFO mode for read and write.
I2CS: supports three targets and each one able located at I2C
interface 0~8.
supports 16 bytes dedicated FIFO mode that only supports write or
read mode and the maximum buffer size is 256 bytes.
support non-FIFO write to shared FIFO read mode. The maximum
shared FIFO size for read is 256 bytes.
The APIs test include: i2c_write(), i2c_read(), i2c_burst_read(),
i2c_burst_write(), i2c_write_read()
