PCI: Put pci_dev in device tree as early as possible
We want to put pci_dev structs in the device tree as soon as possible so for_each_pci_dev() iteration will not miss them, but driver attachment needs to be delayed until after pci_assign_unassigned_resources() to make sure all devices have resources assigned first. This patch moves device registering from pci_bus_add_devices() to pci_device_add(), which happens earlier, leaving driver attachment in pci_bus_add_devices(). It also removes unattached child bus handling in pci_bus_add_devices(). That's not needed because child bus via pci_add_new_bus() is already in parent bus children list.
