The current implementation uses the runtime PM autosuspend feature with a default timeout set to 50ms. This really doesn't makes sense, as it's a USB driven host device, which needs it rtsx USB device (parent device) to be runtime resumed to provide power to the card. In practise, using the autosuspend or any async runtime PM suspend method, means unnecessary delaying the host device and thus the parent, to be runtime suspended when a card is removed/powered off. For this reasons, let's simply drop the support for runtime PM autosuspend and tell the mmc core to use synced runtime PM suspend methods, via setting MMC_CAP_SYNC_RUNTIME_PM during probe. Moreover, as the mmc core nowadays deploys runtime PM reference counting of the mmc host device, convert ->set_ios() to use the more lightweight pm_runtime_get_noresume() and pm_runtime_put_noidle() APIs.
