ARM: dts: imx28-evk: add vmmc-supply for mmc device

Add vmmc-supply for mmc device, so that the power to mmc slot can be
turned on by mmc driver if bootloader hasn't done it.

Also remove "okay" status for mmc1/ssp1, as the device has pin conflict
with gpmi-nand.  Actually the device is already disabled since the
mxs-mmc driver adopts pinctrl support because there is no pinctrl setup
for the device in dts.  Make this explicit by removing "okay" status.
