Reset cause is a very important information - we can know if the
processor gets a watchdog, or if a power on happened. The last one can
address to hiddden issues with the power supply.

I understand that less redundant information is better, but this is very
important info and it cannot be used only if DEBUG is set. IMHO we
should let it as it is - it helps us when something bad happens.
