PCI: endpoint: Make struct pci_epf_ops in pci_epf_driver const

Browse source

The pci_epf_ops struct contains a set of callbacks that are used by the
pci_epf_driver, and is never modified by the EPF core itself.

Marking the struct pointer const allows EPF drivers to declare their
pci_epf_ops struct to be const.

This allows the struct to be placed in the read-only section. Which
for example brings some security benefits as the callbacks can not be
overwritten.
