dev: refactor pci config space for sysfs scanning

Sysfs on ubuntu scrapes the entire PCI config space
when it discovers a device using 4 byte accesses.
This was not supported by our devices, in particular the NIC
that implemented the extended PCI config space.  This change
allows the extended PCI config space to be accessed by
sysfs properly.
