PCI: generic: Allow multiple hosts with different map_bus() methods

Browse source

The generic driver kept a global struct pci_ops ("gen_pci_ops") which it
patched with the .map_bus() method appropriate for the bus device.  This is
a problem when we have two different types of bus devices: the .map_bus()
method for the last device probed clobbers the method for previous devices.
The result is that only the last bus device probed has the correct
.map_bus(), and the others fail.

Move the struct pci_ops into the bus-specific structure and initialize a
pointer to it when the bus device is probed.
