[RFC PATCH v4 8/8] hw/arm/tosa: Make TYPE_TOSA_MISC_GPIO a plain QDev

[Philippe Mathieu-Daudé]

TYPE_TOSA_MISC_GPIO doesn't need to be a SysBus device,
make it a plain QDev.

Signed-off-by: Philippe Mathieu-Daudé <f4...@amsat.org>

RFC because having to pass MachineState and call
object_property_add_child() simply makes things more
complex... but it seems to cleaner QOM design.
