Since milkymist-memcard 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.
