PCI devices may support more capabilities of the same type (for
example PCI_CAP_ID_VNDR) and there was no way to discover all of them.
This commit adds a new API pci_find_next_capability which provides
this functionality. It would typically be used like so:
for (pos = pci_find_capability(pci, PCI_CAP_ID_VNDR);
pos > 0;
pos = pci_find_next_capability(pci, pos, PCI_CAP_ID_VNDR)) {
...
}
