mmc: omap: fix for bus width which improves SD card's peformance.
This patch improves low speeds for SD cards.
OMAP-MMC controller's can support maximum bus width of '8'. when bus
width is mentioned as "8" in controller data,the SD stack will check
whether bus width is "4" and if not it will set bus width to "1" and there
by degrading performance. This patch fixes the issue and improves the
performance of SD cards.
