sdmmc cd pin is configured as RK_FUNC_GPIO which is wrong and
indeed failed to detect the sdcard on the board with below error

  Card did not respond to voltage select!

So, fix it by replacing RK_FUNC_GPIO with RK_FUNC_1 which
is already defined in rk3399.dts so make use of same like
other boards.

Add these changes in -u-boot.dtsi to make Linux sync easy for future
changes.
