In commit commit d2c05f50e12f ("mmc: omap_hsmmc: Set 3.3V for IO voltage")
was changed 3.0V IO voltage to 3.3V but it was not done on all places in
omap_hsmmc driver. That commit broke eMMC support on Nokia N900.

This patch fixes that problematic commit and changes 3.0V to 3.3V on all
remaining places in omap_hsmmc driver.
