soc/amd/*/chipset.cb: don't call dummy device functions host bridges 

Function 0 of the devices that have the bridges to other buses are dummy
functions that can be left enabled to not have to shuffle around the
device function numbers when the first PCI bridge on those devices isn't
enabled. Those dummy device functions are however not PCI host bridges,
so change the comments from 'Dummy Host Bridge' to 'Dummy device
function'.
