PCI: Make current and maximum bus speeds part of the PCI core
Move the max_bus_speed and cur_bus_speed into the pci_bus. Expose the values through the PCI slot driver instead of the hotplug slot driver. Update all the hotplug drivers to use the pci_bus instead of their own data structures. Signed-off-by: Matthew Wilcox <willy@linux.intel.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
