Make use of the common CF9 reset in SOC_INTEL_COMMON_RESET. Also implement board_reset() as a "full reset" (aka. cold reset) as that is what was used here for hard_reset(). Drop soc_reset_prepare() thereby, as it was only used for APL. Also, move the global-reset logic. We leave some comments to remind us that a system_reset() should be enough, where a full_reset() is called now (to retain current behaviour) and looks suspicious. Note, as no global_reset() is implemented for Denverton-NS, we halt there now instead of issuing a non-global reset. This seems safer; a non-global reset might result in a reset loop.
