mci: improve packing of struct mci
rca will be at least 4-byte aligned due to being after a 4-byte member.
It's only 2 byte long though and followed by another 4 byte member,
wasting 2 bytes. Fill those up with the two 1-byte bool members we have.
This includes a change of type for high_capacity: This is ok, because
only 0 or 1 are ever saved into it.
