It's pointless to repatch all of that in this file if we *know* those are already working.

By taking those changes and testing on mainline, I couldn't get mmc working and was not confident about ethernet changes, I2C changes were verified and boot test was done (with DT clock series). I posted only the changes that I felt confident. Basic DT file and I2C are dependency for others, it was necessary to remove dependencies at the earliest.
