[PATCH 02/22] hw/intc/apic: Pass CPU using QOM link property

[Philippe Mathieu-Daudé <philmd@xxxxxxxxxx>]

QOM objects shouldn't access each other internals fields
except using the QOM API.

Declare the 'cpu' and 'base-addr' properties, set them
using object_property_set_link() and qdev_prop_set_uint32()
respectively.
