The reset controller is part of the RCC (Reset & Clock Controller) IP.
In this version, I only provided the reset registers to the reset
controller driver, but as per Andreas Färber remark, I should avec a
single DT node for both the resets and clocks.

In the next version I am preparing, the defines doesn't look as
trivial as in this version, GPIOA_RESET being 128 for instance.

Is it fine for you if I keep the defines part of the binding?
