hw: move headers to include/
Many of these should be cleaned up with proper qdev-/QOM-ification.
Right now there are many catch-all headers in include/hw/ARCH depending
on cpu.h, and this makes it necessary to compile these files per-target.
However, fixing this does not belong in these patches.

-/**
- * DeviceClass:
- * @props: Properties accessing state fields.
- * @realize: Callback function invoked when the #DeviceState:realized
- * property is changed to %true. The default invokes @init if not %NULL.
- * @unrealize: Callback function invoked when the #DeviceState:realized
- * property is changed to %false.
- * @init: Callback function invoked when the #DeviceState::realized property
- * is changed to %true. Deprecated, new types inheriting directly from
- * TYPE_DEVICE should use @realize instead, new leaf types should consult
- * their respective parent type.
- *
- * # Realization #
- * Devices are constructed in two stages,
- * 1) object instantiation via object_initialize() and
- * 2) device realization via #DeviceState:realized property.
- * The former may not fail (it might assert or exit), the latter may return
- * error information to the caller and must be re-entrant.
- * Trivial field initializations should go into #TypeInfo.instance_init.
- * Operations depending on @props static properties should go into @realize.
- * After successful realization, setting static properties will fail.
- *
- * As an interim step, the #DeviceState:realized property is set by deprecated
- * functions qdev_init() and qdev_init_nofail().
- * In the future, devices will propagate this state change to their children
- * and along busses they expose.
- * The point in time will be deferred to machine creation, so that values
- * set in @realize will not be introspectable beforehand. Therefore devices
- * must not create children during @realize; they should initialize them via
- * object_initialize() in their own #TypeInfo.instance_init and forward the
- * realization events appropriately.
- *
- * The @init callback is considered private to a particular bus implementation
- * (immediate abstract child types of TYPE_DEVICE). Derived leaf types set an
- * "init" callback on their parent class instead.
- *
- * Any type may override the @realize and/or @unrealize callbacks but needs
- * to call the parent type's implementation if keeping their functionality
- * is desired. Refer to QOM documentation for further discussion and examples.
- *
- * <note>
- *   <para>
- * If a type derived directly from TYPE_DEVICE implements @realize, it does
- * not need to implement @init and therefore does not need to store and call
- * #DeviceClass' default @realize callback.
- * For other types consult the documentation and implementation of the
- * respective parent types.
- *   </para>
