From: Stephen Warren <swarren@xxxxxxxxxx>
Tegra124 has 4 MMC controllers just like previous versions of the SoC.
Note that there are some non-backwards-compatible HW differences, and
hence a new DT compatible value must be used to describe the HW.
Also enable the relevant controllers in the Venice2 board DT.
power-gpios property suggested by Thierry Reding.

v2: Add power-gpios to SD card node, suggested by Thierry.
