As we are post -rc1 I will repost this series as a v6 after rebasing.

While at it I'll get rid of this extra new line but that's basically
all what I plan to change.

As this series brings the basics for more RZN1 support (because of
this specific sysctrl patch), it is kind of a base for more
contributions which are in the pipe (UART, USB, RTC, Switch, etc) so
hopefully it is now ready to be accepted.

Thanks,
Miquèl
