Yeah, it is not hard. But it is annoying and sometimes
I felt it is a waste of time to add a device id to the
reset-simple driver.

It is not 1 register per node, but a contiguous range.
In most SoC satisfy the requirement, only one reset
device is added. This is what the reset-simple handle.
1 register per node is too crazy for everyone....
