Note that the version 1 of this patch had a device, and I argued against
that patch on the basis that anything under /sys/devices/ should
reflect an actual part of the hardware, which socinfo by itself
does not.

I believe the best way to represent this really is to have
a device (platform or other, I don't care) that:

* represents the SOC in its entirety
* has the subdevices that are part of the SOC as direct
  or indirect children
* can be identified easily as a SOC (through one of
  its name, its place in the hierarchy or its bus_type)
* has the standard device attributes proposed in Maxime's
  patch.
