Subject: [PATCH v2 2/2] arm64: dts: mt8173: elm: Use aliases to mmc nodes

fa2d0aa96941 ("mmc: core: Allow setting slot index via device tree alias")
allows the use of aliases to number SD/MMC slots. This patch use aliases
to mmc nodes so the partition name for eMMC and SD card will be consistent
across boots.
