So far, even if our card was not in use, we didn't shut down our MMC controller, which meant that it was still active and clocking the bus. While this obviously means that we could save some power there, it also creates issues when it comes to EMC control since we'll have a perfect peak at the card clock rate. Let's implement runtime_pm with autosuspend so that we will shut down the controller when it's not been in use for quite some time.
