[Qemu-devel] [PATCH for-1.4?] isa: QOM'ify isa_bus_from_device()

["Andreas Färber" <afaerber@suse.de>]

DeviceState::parent_bus is document as private and should be accessed
through qdev_get_parent_bus(). Use a DEVICE() cast instead of accessing
ISADevice's qdev field directly. Use ISA_BUS() in place of DO_UPCAST().
