[ Upstream commit f1bb924e8f5b50752a80fa5b48c43003680a7b64 ]
Similar to other G12B devices using the W400 dtsi, I see reports of mmc0 tuning errors on VIM3 after a few hours uptime:
[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
I do not see the same on VIM3L, so remove sd-uhs-sdr50 from the common dtsi to silence the error, then (re)add it to the VIM3L dts.
