Mark switch cases where we are expecting to fall through.

This patch fixes the following warning (Building: allmodconfig i386):

drivers/pci/hotplug/ibmphp_res.c: In function ‘update_bridge_ranges’:
drivers/pci/hotplug/ibmphp_res.c:1943:16: warning: this statement may fall through [-Wimplicit-fallthrough=]
function = 0x8;
~~~~~~~~~^~~~~
drivers/pci/hotplug/ibmphp_res.c:1944:6: note: here
case PCI_HEADER_TYPE_MULTIBRIDGE:
^~~~
