This shouldn't exist to start with. It should be using a qemu_irq, like the
other GPIO pins do, and probably wants to be implemented outside sd.c anyway.
The whole point of chip selects is to allow multiple devices on the same bus.
See stellaris_ssi_bus for an example of a bus multiplexer with chip selects.
