Fix memory card not properly attaching on init. (#433)

* Fix memory card not properly attaching on init.

Previously the card status was forced to ready which caused quite a bit of default state getting set properly,
reverting that and setting mCardCommand to `COMM_ATTACH_e` allows the memory card system to properly probe and
detect the card status.

A companion fix in aurora addresses the "Memory Card corrupted" error message.

* Update aurora
