PCI: Add pci_get_domain_bus_and_slot() stub

Browse Source 
The coretemp driver build fails when CONFIG_PCI is not enabled because it
uses a function that does not have a stub for that config case, so add the
function stub.

  ../drivers/hwmon/coretemp.c: In function 'adjust_tjmax':
  ../drivers/hwmon/coretemp.c:250:9: error: implicit declaration of function 'pci_get_domain_bus_and_slot' [-Werror=implicit-function-declaration]
    struct pci_dev *host_bridge = pci_get_domain_bus_and_slot(0, 0, devfn);
  ../drivers/hwmon/coretemp.c:250:32: warning: initialization makes pointer from integer without a cast [enabled by default]
    struct pci_dev *host_bridge = pci_get_domain_bus_and_slot(0, 0, devfn);
