Allwinner H6 features 3 SD/MMC controllers. The first and second ones are similar to the ones on the Allwinner A64/H5 SoCs, and the third one adds the function to use EMCE (EMbedded Crypto Engine) on the Allwinner H6 chip to do full-disk encryption.
Enable basic MMC support on Allwinner H6. Higher speed bins are not supported, similar to A64/H5. EMCE is also not supported, and keeps its bypassed status by default.
