You might want to check what happens in omap off-idle mode in these cases
and see if enabling OMAP_PIN_OFF_INPUT_PULLDOWN makes any difference in
power consumption in off state. That probably does not matter unless the
floating lines cause the eMMC to do something on it's own :)
Or OMAP_PIN_OFF_OUTPUT_LOW actually.
One more time.. Most likely OMAP_PIN_OFF_INPUT_PULLDOWN is safer
in general as the OMAP_PIN_OFF_OUTPUT_LOW does not work for all
pins. According to the TRM, OMAP_PIN_OFF_OUTPUT_LOW only works
for pins where at least one of the mux modes supports output
mode.
While eMMC is on, it is better if the lines are pulled up,
irrespective of whether OMAP is OFF, just to keep to the
MMC specification.
