Sean Anderson 3f6fb77175 mmc: sandbox: Add support for writing
This adds support writing to the sandbox mmc backed by an in-memory
buffer. The unit test has been updated to test reading, writing, and
erasing. I'm not sure what MMCs erase to; I picked 0, but if it's 0xFF
then that can be easily changed.
