I struggled a bit to understand what's to gain with this change, but it makes
more sense when we consider the changes made in the next patch (where a
TYPE_PPC4xx_HOST_BRIDGE macro is introduced to match the "ppc4xx-host-bridge"
name).

I also understand the comments Phil made in version 1. We have several QOM names
that are too similar ("ppc4xx-pci-host", "ppc4xx-host-bridge" in the next patch,
"ppc440-pcix-host" in patch 4), all of them being PCI host bridges. I am 
uncertain
whether renaming the QOM name of these devices to make them less similar is 
worth
it.

Matching the macro names with the actual QOM name is a step in the right 
direction
though.
