qdev: register properties as class properties

Browse source 
Use class properties facilities to add properties to the class during
device_class_set_props().

qdev_property_add_static() must be adapted as PropertyInfo now
operates with classes (and not instances), so we must
set_default_value() on the ObjectProperty, before calling its init()
method on the object instance.

Also, PropertyInfo.create() is now exclusively used for class
properties. Fortunately, qdev_property_add_static() is only used in
target/arm/cpu.c so far, which doesn't use "link" properties (that
require create()).
