Please don't waste time to review the commit message above!

The subject and the commit message is not aligned with the commit update

I need to rework it in a V2. I'm waiting few days before sending the V2,
allowing people to comment V1.

For V2 I will probably copy/past the commit message of:

[PATCH 1/5] dt-bindings: remoteproc: st,stm32-rproc: Rework reset declarations

Arnaud
