PCI: alpha: use generic pci_enable_resources()
Use the generic pci_enable_resources() instead of the arch-specific code.
Unlike this arch-specific code, the generic version:
- skips resources unless requested in "mask"
- skips ROM resources unless IORESOURCE_ROM_ENABLE is set
- checks for resource collisions with "!r->parent"
