[Skiboot] [PATCH] zaius: Add BMC description

[Andrew Jeffery]

Frederic reported that Zaius was failing with a NULL dereference when
trying to initialise IPMI HIOMAP. It turns out that the BMC wasn't
described at all, so add a description.

Tested on zaius1, which reached petitboot with the patch applied.
