fdc: QOM'ify some more
Introduce type constant and avoid DO_UPCAST(), container_of(), and use DEVICE() to avoid accessing parent qdev directly. Signed-off-by: Hu Tao <hutao@cn.fujitsu.com> [AF: Renamed parent field and avoided repeated SYS_BUS_DEVICE() casts] Signed-off-by: Andreas Färber <afaerber@suse.de>
