[patch cut] Simplified SDIO spec v.2.00 (section 6.14 - Bus State Diagram) suggests, that initialization commands (CMD5, CMD3) are not accepted in CMD state. As the card stays in that state on powered suspend (no resetting CMD52 nor power cycle is issued) then reinitialization should be entirely skipped on resume unless the power was lost between suspend and resume (or card was temporarily removed from the slot).
