mmc: sdhci-pci: enable runtime PM for Medfield SDIO
Runtime PM for SDIO is no longer enabled by default (see 5c7f0e083d2d98ba14ddd10e88f001a0ead4cae4) so it must now be enabled per platform, in this case Medfield uses it. Signed-off-by: Adrian Hunter <adrian.hunter@intel.com> Signed-off-by: Chris Ball <cjb@laptop.org>
