dt-bindings: exynos-dw-mshc-common: add exynos7885 variants

Some Samsung Exynos boards using the arm64 architecture have DW MMC controllers configured for a 32-bit data bus but a 64-bit FIFO. On these systems the 64-bit FIFO registers must be accessed in two 32-bit halves.

Add two new compatible strings, "samsung,exynos7885-dw-mshc" and "samsung,exynos7885-dw-mshc-smu" respectively, to denote exynos7885 boards that need this quirk. But it's very possible that all "samsung,exynos7-dw-mshc" boards are actually affected.
