hw/core: deprecate old reset functions and introduce new ones

Browse source 
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.
