Subject: [PATCH 1/2] dt-bindings: mmc: sunxi: Add D1 MMC and eMMC compatibles

D1 contains variants of the usual sunxi MMC controller. The eMMC
controller has the same parameters as the A100 eMMC controller. The
other controllers have a DMA address shift like on A100, but they have
a smaller 13-bit size field, making them a new incompatible variant.
