reset: Use ResetType for qemu_devices_reset() and MachineClass::reset()

Browse source 
Currently, both qemu_devices_reset() and MachineClass::reset() use
ShutdownCause for the reason of the reset. However, the Resettable
interface uses ResetState, so ShutdownCause needs to be translated to
ResetType somewhere. Translating it qemu_devices_reset() makes adding
new reset types harder, as they cannot always be matched to a single
ShutdownCause here, and devices may need to check the ResetType to
determine what to reset and if to reset at all.

This patch moves this translation up in the call stack to
qemu_system_reset() and updates all MachineClass children to use the
ResetType instead.
