Mike Smith 9992d96f25 Fix detection of the card-ready-for-command state. Use an ultimate
timeout closer to the 1-second value that AMI use in their Linux
driver, and mark the mailbox structures as volatile so that gcc
doesn't over-optimise access to them.

This should fix the "controller wedged" bug.
