    broadcom/cygnus: Implement I2C driver
    
    BUG=chrome-os-partner:35810
    BRANCH=purin
    TEST=Enable I2C1, reset devboard codec, read a register.
         Here is the code that demonstrates how I2C works:
    
    	i2c_init(1, 100*KHz);
    	mdelay(50);
    
    	int rc = i2c_writeb(1, 0x18, 1, 0x80); // reset codec
    	printk(BIOS_INFO, "I2C reset rc=%d\n", rc);
    	mdelay(50);
    	uint8_t data = 0;
    	rc = i2c_readb(1, 0x18, 43, &data);
    	printk(BIOS_INFO, "I2C read rc=%d data=%x\n", rc, data); // data == 0x80
