[PATCH -next] PCI: rpadlpar: Make some functions static

[Wei Yongjun]

The sparse tool report build warnings as follows:

drivers/pci/hotplug/rpadlpar_core.c:355:5: warning:
 symbol 'dlpar_remove_pci_slot' was not declared. Should it be static?
drivers/pci/hotplug/rpadlpar_core.c:461:12: warning:
 symbol 'rpadlpar_io_init' was not declared. Should it be static?
drivers/pci/hotplug/rpadlpar_core.c:473:6: warning:
 symbol 'rpadlpar_io_exit' was not declared. Should it be static?

Those functions are not used outside of this file, so marks them
static.
Also mark rpadlpar_io_exit() as __exit.
