3.19.8-ckt6 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Joakim Tjernlund <Joakim.Tjernlund@transmode.se>

commit 8e91125ff3f57f15c6568e2a6d32743b3f7815e4 upstream.

Support for 8BIT bus with was added some time ago to sdhci-esdhc but
then missed to remove the 8BIT from the reserved bit mask which made
8BIT non functional.

Fixes: 66b50a00992d ("mmc: esdhc: Add support for 8-bit bus width and..")
