hw/core: deprecate old reset functions and introduce new ones
Deprecate device_legacy_reset(), qdev_reset_all() and qbus_reset_all() to be replaced by new functions device_cold_reset() and bus_cold_reset() which uses resettable API. Also introduce resettable_cold_reset_fn() which may be used as a replacement for qdev_reset_all_fn and qbus_reset_all_fn(). Following patches will be needed to look at legacy reset call sites and switch to resettable api. The legacy functions will be removed when unused.
