mmc: sdhci: Remove misleading comment about resets

Browse source 
In SDHCI specification section 3.10.1 Error Interrupt Recovery, the flow
chart shows Software Reset for CMD separately and before Software Reset for
DAT, so the comment "Spec says we should do both at the same time" is not
correct. Remove it.
