Subject: [PATCH v1 4/5] arm64: dts: exynos8895: add a node for mmc

Add an MMC node in order to allow devices with that SoC to make use of
it. It's typically used as a secondary storage option for SD cards. In
the vendor kernels, it's labelled as mmc_2, but since there don't seem to
be any other blocks, treat it as the only MMC.
