Subject: [PATCH] PCI: add stub for pci_set_consistent_dma_mask()

From: Randy Dunlap <randy.dunlap@...cle.com>

When CONFIG_PCI=n, there is no stub for pci_set_consistent_dma_mask(),
so add one like other similar stubs.  Otherwise there can be build errors,
as here:

linux-next-20080630/drivers/ssb/main.c:1175: error: implicit declaration of function 'pci_set_consistent_dma_mask'
