[PATCH 01/11] hw/core/null-machine: Define machine as generic QOM type

["Philippe Mathieu-Daudé" <philmd@linaro.org>]

While DEFINE_MACHINE() is a succinct macro, it doesn't
allow registering QOM interfaces to the defined machine.
Convert to the generic DEFINE_TYPES() in preparation to
register interfaces.
