Subject: [PATCH v6 12/13] PCI: brcmstb: Change field name from 'type' to 'soc_base'
The 'type' field used in the driver to discern SoC differences is
confusing; change it to the more apt 'soc_base'. The 'base' is because
some SoCs have the same characteristics as previous SoCs so it is
convenient to classify them in the same group.
