mmc: sdhci: Add a quirk for broken command queuing
commit 75d27ea1 upstream. Command queuing has been reported broken on some systems based on Intel GLK. A separate patch disables command queuing in some cases. This patch adds a quirk for broken command queuing, which enables users with problems to disable command queuing using sdhci module parameters for quirks.
