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.
