Subject: [PATCH] arm64: dts: mt8173: add aliases for mt8173 mmc device nodes

Doing this makes them get enumerated in a deterministic order so that
the assigned name in /dev that the mmc devices get assigned is
consistent across reboots.

See ead9f7d7ea9 ("arm64: dts: qcom: sc7180: Assign numbers to eMMC and
SD") for similar work.
