frv: 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:
- checks PCI_NUM_RESOURCES (11), not 6, resources
- skips resources that have neither IORESOURCE_IO nor IORESOURCE_MEM set
- skips ROM resources unless IORESOURCE_ROM_ENABLE is set
- checks for resource collisions with "!r->parent"
