ARM: dts: sun7i: Olimex A20-SOM-EVB: Enable mmc3 (baseboard SD socket)
The Olimex A20-SOM-EVB is an evaluation board for the Olimex A20-SOM system-on-module. The baseboard provides a full-size SD socket (connected to mmc3) in addition to the micro-SD socket on the SOM itself (which is connected to mmc0). Enable the mmc3 controller in the dts.
