PCI: shpchp: Iterate over all devices in slot, not functions 0-7
Iterate through devices in a slot by using the upstream bridge's
"bus->devices" list instead of assuming they are functions 0-7. It's
possible there are several slots on the same pci_bus, so restrict it to
only devices matching this slot's device number.
ARI (which allows functions 0-255) is a PCIe-only feature, and this is
a PCI hotplug driver, so we shouldn't find anything other than functions
0-7, but it's better to iterate the same way as other hotplug drivers.
