MMC_POWER_ON is a noop, no need to set the power pin again.

MMC_POWER_OFF/MMC_POWER_UP turn the power OFF/ON, there is nothing to change
when ios->power_mode==MMC_POWER_ON.

Also changed indentation for the switch (CodingStyle), because there is no other
switch statement in this driver.

Perhaps also a WARN_ON() or something in the default case to catch bad invokations?
