integration/soc/add_sdcard: Add an interrupt for command completion 

This is useful for long-running commands generally and in particular
for those without any data transfer, such as erase.  It is a
level-sensitive interrupt because that makes it a little harder to
lose interrupts due to incorrect programming.
