As part of some ongoing sun4u work, I need to be able to wire the fw_cfg
IO interface to a separate IO space by instantiating the qdev device instead
of calling fw_cfg_init_io(). This patchset brings FW_CFG_IO in line with
FW_CFG_MEM and tidies up the realize methods accordingly.
Signed-off-by: Mark Cave-Ayland <mark.cave-ayl...@ilande.co.uk>

- Add Reviewed-By from Laszlo for patch 2
- Fix assert() when instantiating > 1 fw_cfg device (new patch 3)
- Rename fw_cfg_init1() to fw_cfg_common_realize() as part of patch 4

fw_cfg: move assert() and linking of fw_cfg device to the machine
into instance_init()
fw_cfg: move qdev_init_nofail() from fw_cfg_init1() to callers
fw_cfg: move QOM type defines and fw_cfg types into fw_cfg.h
