commit ef581f3c543027fce1581a8036ca82e4259c52d2 from
https://github.com/altera-opensource/linux-socfpga.git
[upstream commit ab37b08d91f5bb180ae6c05091ed2209700939c6]
The I2C pins on Intel's SoCFPGA platform are not connected to GPIOs and
thus cannot be recovered by the standard GPIO method.
Document the "intel,socfpga-i2c" binding.
