pci/shpc: convert SHPC hotplug to use hotplug-handler API

Split shpc_device_hotplug() into hotplug/unplug callbacks
and register them as "hotplug-handler" interface implementation of
PCI_BRIDGE_DEV device.

Replace pci_bus_hotplug() wiring with setting link on PCI BUS...

qdev:pci: refactor PCIDevice to use generic "hotpluggable" property

hw/pci: fix error flow in pci multifunction init

Scenario:
- There is a non multifunction pci device A on 00:0X.0.
- Hot-plug another multifunction pci device B at 00:0X.1.
- The operation will fail of course.
- Try to hot-plug the B device 2-3 more times, qemu will crash....

qdev: Drop misleading qbus_free() function

Same reasoning as commit 02a5c4c97422b40034f31265e0f139f7846172a8
("qdev: Drop misleading qdev_free() function"). The qbus_free()
function removes the child from the namespace and decrements the
reference count. It does not, however, guarantee to free the child...

pci: do not export pci_bus_reset

qbus_reset_all can be used instead. There is no semantic change
because pcibus_reset returns 1 and takes care of the device
tree traversal.

pci: clean up resetting of IRQs

pci_device_reset will deassert the INTX pins, and this will make the
irq_count array all-zeroes. Check that this is the case, and remove
the existing loop which might even unsync irq_count and irq_state.

qdev: switch reset to post-order

Post-order is the only sensible direction for the reset signals.
For example, suppose pre-order is used and the parent has some data
structures that cache children state (for example a list of active
requests). When the reset method is invoked on the parent, these caches...
