Subject: mmc: sdhci-esdhc: Make 8BIT bus work
From: Joakim Tjernlund <Joakim.Tjernlund@xxxxxxxxxxxx>
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..")
