Keeping the power to the SDIO card during system wide suspend, consumes energy. Especially on battery driven embedded systems, this can be a problem. Therefore, let's change the behaviour into allowing the SDIO card to be powered off, unless WOWL is supported and enabled. Note that, the downside from this change, is that during system resume the SDIO card needs to be re-initialized and the FW must be re-programmed. Even if this may take some time to complete, it should we worth it, rather than draining the battery. Signed-off-by:
