This seems like a list with the potential to grow unbounded. I think it 
would be better for the platforms to 'select RESET_SIMPLE' rather than 
trying to guess all users in one big kconfig line.

Hmm. I think it would be useful for new devices if there were have a way 
to specify this in devicetree.

Are plans to have a "simple-reset" compatible binding for new devices?
