mmc: sunxi: Add support for A83T eMMC (MMC2)
The third MMC controller (MMC2) on the Allwinner A83T SoC is slightly different. It supports a wider 8-bit bus, has a dedicated controllable reset pin for eMMC, and a "new timing mode" which is supposed to deliver better signals and thus better performance. Add a compatible for this one to use the new timing mode not found in the other controllers.
