    hw/sd/pl181: Reset SD card on controller reset
    
    Since pl181 is still using the legacy SD card API, the SD
    card created by sd_init() is not plugged into any bus. This
    means that the controller has to reset it manually.
    
    Failing to do this mostly didn't affect the guest since the
    guest typically does a programmed SD card reset as part of
    its SD controller driver initialization, but meant that
    migration failed because it's only in sd_reset() that we
    set up the wpgrps_size field.
