We should add the sdmmc but enabling it, since the sdmmc and
uart2 ie reusing the same pin.
That will cause the debug information can't display on console.
Anyway, you only need add the okay status if someone wants to enable
the sdmmc.
e.g.
if you use the adb to debug and run with android os.
you can add the
status = "okay" to enable the sdmmc for sd card working.
