RTC devices could provide battery-backed memory that can be used for

Add a new reboot-mode back-end that uses RTC to store the reboot-mode
magic value. The driver also supports both endianness modes.

But I think it would be better to put this device as a child of the
rtc, so it is more obvious that they are related. It also avoids the
phandle. What do you think?
Hi Simon and thanks for reviewing the code,
I think the idea is not bad, however, would be ok to consider the
recommendation as improvement opportunity and merge this as
it is for now? I'm a bit busy with some other stuff now and I could
start implementing this some time later. At least it would help me since
this are on the mailing list since Dec 2019 :).
