mmc: sdio: fully reconfigure oldcard on resume
On resume, let mmc_sdio_init_card go all the way, instead of skipping the reconfiguration of the card's speed and width. This is needed to ensure cards wake up with their clock reconfigured (otherwise it's kept low). This patch also removes the explicit bus width reconfiguration on resume, since now this is part of mmc_sdio_init_card.
