It is helpful to know what device, if any, a software node is tied to, so
let's store a pointer to the device in software node structure. Note that
children software nodes will inherit their parent's device pointer, so we
do not have to traverse hierarchy to see what device the [sub]tree belongs
to.

We will be using the device pointer to locate GPIO lookup tables for
devices with static properties.

If some device core person like Rafael and/or Greg can ACK it I can
apply this patch to the GPIO tree.

I don't have any concerns regarding this, so please feel free to add

to the commit when you apply it.

Thanks!
