Subject: mmc: sdhci-esdhc: Make 8BIT bus work

From: Joakim Tjernlund <[email protected]>

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..")
