What exactly do you mean by "soc"-level registers?

I propose we do it by defining the first (and ideally only, but that's 
another argument) entry in ranges as the immr, and getting rid of /soc/reg.

And why can't it do that on 82xx?

The /soc node is misnamed; it should really be /immr.  Why do we need 
these particular registers to be in /soc/reg rather than a subnode?
