The defines for the "indices of the base address regions" don't add much to the readability of the code. They are only used in the pci_resource_start() calls to get the base address for the various io regions and the names of the variables provide adequate documentation.
Remove the defines and just use the open-coded values for the BARs. Also, remove the incomplete comment above the initialization of the variables.
