mmc: exynos_dw_mmc: add compatible for exynos7870-dw-mshc-smu
Exynos7870 is documented in upstream dt-schema. Add it in the U-Boot
driver.
Note that here it seems that Exynos7 DW MMC is perfectly compatible with
Exynos7870 DW MMC. It's not always true, especially in SDIO cards where
data from a 64-bit FIFO is read in two 32-bit halves [1]. Since SDIO
isn't used or implemented here, it's oblivious. But upstream's schema
considers that quirk, so that compatible is followed.
