Nope, that's just an outright bug in the raspi support. I'd recommend several
things here:

1. Open an issue in the github issue tracker[0]
2. Cook up a patch! It looks like this might have to do with assumptions made
   in meta-phosphor/conf/distro/openbmc-phosphor.conf, as the raspi uses a
   different kernel tree to the ASPEED SoCs
3. For better or worse patches are submitted via Gerrit[1], so push your patch
   there

Make sure to speak up here or on IRC if you get stuck :)
