Subject: [PATCH v5 3/3] arm64: dts: exynos: fix wrong mmc compatible in
 exynos7885.dtsi

This DW-MMC variant is not actually compatible with
"samsung,exynos7-dw-mshc-smu", and requires an additional quirk to handle
very short data transfers, typically used by SDIO cards. Update the
compatible string to "samsung,exynos7885-dw-mshc-smu" to reflect this fact.
