[PATCH v2 2/3] ARM64: dts: amlogic: eMMC support for all Tronsmart Vega S95 devices

[martin.blumenstingl@googlemail.com (Martin Blumenstingl)]

This adds eMMC support for all Tronsmart Vega S95 devices using
sd_emmc_c. This is implemented similar to the p20x boards (meaning it
uses fixed regulators).
