hw/arm/spitz: Fix reset handling
Using the CPU reset handler for resets triggered by writing into gpio pins other than GPIO01 is not appropriate and does not work, since the reset triggered by writing into GPIO01 is configurable. Use a separate reset handler for spitz to reset the entire system and not just the CPU.
