ARM: Kirkwood: topkick: Enable i2c bus.
Add a DT node for I2C and pinctrl hog for the pins. There appears to be an i2c bus on topkick with a device on it: i2cdetect 0 WARNING! This program can confuse your I2C bus, cause data loss and worse! I will probe file /dev/i2c-0. I will probe address range 0x03-0x77. Continue?
