This was initially the idea for the soc_device, but we've stopped
using it as the parent for the on-chip devices a while ago.

Just register the device for identification here, and use
of_platform_default_populate with a NULL parent as most others do.

We should also investigate whether we can convert the three other
at91 variants to do the same without breaking expectations in user space.
