mmc: sdhci: Add a quirk for broken command queuing

commit 75d27ea1abf7af3cc2cdec3513e74f52191605c8 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.
