Current devices using the W400 dtsi show mmc tuning errors:
[12483.917391] mmc0: tuning execution failed: -5
[30535.551221] mmc0: tuning execution failed: -5
[35359.953671] mmc0: tuning execution failed: -5
[35561.875332] mmc0: tuning execution failed: -5
[61733.348709] mmc0: tuning execution failed: -5
Removing "sd-uhs-sdr50" from the SDIO node prevents this. We also add
keep-power-in-suspend to the SDIO node and fix an indentation.

This could use a Fixes tag so it can be backported to stable

Okay, I will send v2 with a fixes tag.
