pci: typedef pcibus_t as uint64_t instead of uint32_t.
This patch is preliminary for 64bit bar. For 64bit bar support, change pcibus_t which represents pci bus addr/size from uint32_t to uint64_t. And also change FMT_pcibus for printf. In pci_update_mapping() checks 32bit overflow. So the check must be updated too. Signed-off-by: NIsaku Yamahata <yamahata@valinux.co.jp> Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>
