Some 80860F14 devices do not support card detect and must rely
completely on GPIO.  Presently the card detect GPIO is used
only to wake-up from runtime suspend.  Change to using
mmc_gpioid_request_cd() which will cause the SDHCI driver to
prefer the GPIO to the host controller's native card detect.
