Sorry for the noise here:), but I find there is some mmc stuff
which confuse me. Maybe Randy could elaborate more?

Your sdmmc claims to support UHS-I mode like sd-uhs-sdr104, etc, which
will ask dw_mmc to switch vqmmc from 3V3 to 1V8 after sending CMD11.

But the vqmmc is vccio_sd which is fixed as 3V3? :)
