mmc: sdhci: Remove misleading comment about resets

Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2144641

    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.
