	  Enable I2C support on IT51XXX series.
	  Supports nine hosts and three targets and each one able to located
	  at I2C interface0~8.
	  Three I2C targets on design A, B and C. Support 16 bytes dedicated
	  FIFO mode for read/write.
	  Supported Speeds: 50kHz, 100kHz, 400kHz and 1MHz.
	  This driver supports repeated start.

	help
	  This is an option to enable FIFO mode which can reduce the time
	  between each byte to improve the I2C bus clock stretching during
	  I2C transaction.
	  The I2C controller supports two 32-bytes FIFOs,
	  FIFO1 supports I2C 0, and FIFO2 supports other ports.
	  I2C FIFO mode of IT51XXX can support I2C APIs including:
	  i2c_write(), i2c_read(), i2c_burst_read.
