Due to hardware limitation AMD I2C controller can't trigger pending interrupt if interrupt status has been changed after clearing interrupt status bits. So, I2C will lose the interrupt and IO will be timed out. Implements a workaround to disable I2C controller interrupt and re-enable I2C interrupt before existing interrupt handler.
