Instead of getting the BlockDriverState* in the pxa2xx board init
and passing it to the mmc controller's init function, have the
mmc controller get the next IF_SD device and use it if present.
This brings us into line with other SD controller models and
means that we correctly emulate an SD controller with no card
present if the user didn't ask for an SD card.
