Hi,

This series:

* Removes the use of early devices from reference marzen reference DT
* Initialises i2c as a late device (non reference DT boot)
* Moves ethernet controller from SoC to marzen board DT file

Merge:

My plan to merge this is:
* Add r8a7779 patches to an soc branch.
* Rebase a boards branch on top of the soc branch.
* Apply marzen patches, squashing them to into existing commits
  to avoid breaking bisection.

Do not initialise any early devices when using the minimal DT reference
code. Only the delay needs to be initialised.

It is sufficient to initialise i2c as a late device.

The ethernet controller is part of the marzen board so add it to
the dts file.

Applied as described above.
The soc branch was soc5.
The boards branch was boards3.
