PCI: endpoint: Add pci_epf_ops to expose function-specific attrs

Browse source

In addition to the attributes that are generic across function drivers
documented in Documentation/PCI/endpoint/pci-endpoint-cfs.rst, there could
be function-specific attributes that has to be exposed by the function
driver to be configured by the user. Add ->add_cfs() in pci_epf_ops to be
populated by the function driver if it has to expose any function-specific
attributes and pci_epf_type_add_cfs() to be invoked by pci-ep-cfs.c when
sub-directory to main function directory is created.
