SD/MMC host controllers provide a SD Bus to plug SD cards, but don't come with SD card plugged in :) The machine/board object is where the SD cards are created. Since the PXA2xx is not qdevified, for now create the cards in pxa270_init() which is the SoC model. In the future we will move this to the board model.
