[ Upstream commit 2fa17dd09533d5d83201be3229a28c1010a8ea3e ]

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.
