[PATCH 2/3] PCI: fill in bus primary field

[Lucas Stach]

This was erroneously left uninitialzed as nothing was using it.
The i.MX6 PCI driver needs this to be filled properly to decide
if a config space access is allowed for a specific devfn.

This fixes PCI enumeration on the Gateworks GW54xx board.
