The same way you format a USB stick when you insert it.
If you have built-in versus removable, then we should expose that
information to userspace rather than some arbitrary encoding in DT
that 0 means built-in and 1 means removable. Or if you have multiple
slots, then use "label" to provide meaningful slot names.
