arm: mvebu: enable the SD card slot on Armada 370 DB board
The Armada XP DB evaluation board has one SD card slot, directly connected to the SDIO IP of the SoC, so we add a device tree description for it. However, in the default configuration of the board, the SD card slot is not usable: the connector plugged into CON40 must be changed against a different one, provided with the board by the manufacturer. Since such a manual modification of the hardware is needed, we did not enable the SDIO interface by default, and left it to the board user to modify the Device Tree if needed. Since this board is really only an evaluation board for developers and not a final product, it is not too bad.
