During the period of I2c accessing, if the board is reset unexpectedly, and because the I2c client can not reset, the SDA will be always pull down, then it cause I2C bus Exception. Follow the Hi1620 I2C FS chapter 1.8.2 design, add I2C Bus Exception handle function. It will Config SCL and SDA to GPIO, and set the reversal frequency of SCL to 10KHz. The implementation of functions is in edk2-non-osi.
