hw/sd/pxa2xx_mmci: Do not create SD card within the SD host controller

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.
