mips/PCI: replace pci_probe_only with pci_flags
Some architectures (alpha, mips, powerpc) have an arch-specific "pci_probe_only" flag. Others use PCI_PROBE_ONLY in pci_flags for the same purpose. This moves mips to the pci_flags approach so generic code can use the same test across all architectures.
