Subject: [PATCH] hwmon/coretemp: requires CONFIG_PCI

From: Randy Dunlap <rdunlap@...radead.org>

Fix coretemp.c build when CONFIG_PCI is not enabled.
Fixes these build errors:

../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);
