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. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
