The file spapr_pci_vfio.c contains exclusively EEH (Enhanced Error Handling) related functions for VFIO devices on sPAPR platforms. To better reflect its specific purpose and improve code organization, this commit:1. Renames spapr_pci_vfio.c to spapr_pci_vfio_eeh.c 2. Moves spapr_phb_vfio_eeh_reenable() from spapr_pci_vfio_eeh.c to spapr_pci.c, as it's a general PHB operation not specific to VFIO EEH error injection/recovery After this change, spapr_pci_vfio_eeh.c contains only the core VFIO EEH error handling functions, making the file's purpose more focused and clear. This is a refactoring change with no functional impact.

There is a CONFIG_VFIO_PCI in this file that could be replaced with stub definitions. Thanks, C.
