Here are the driver updates to support this new SoC. Since I don't have HW
access, this is a request for testing. The IP cores are backwards compatible to
Gen2. So, as long as the clocks are properly setup and the bus speed is OK,
the rest should work out of the box.

From: Wolfram Sang
Enable the I2C core for this SoC. I add a new type because this version
has new features (e.g. DMA) which will be added somewhen later.

Enable the I2C core for this SoC. It is compitable to Gen2 SoCs, so
reuse the settings.
