mmc: sdio: don't reinitialize nonremovable powered-resumed cards

Upon system resume, SDIO core must reinitialize cards that were
powered off during suspend.

If the card had its power kept during suspend (and thus it is
'powered-resumed'), SDIO core performs only a limited reinitializing,
mainly needed to make sure that the card wasn't removed/replaced.

If a __nonremovable__ card is powered-resumed, we can safely skip the
reinitializing phase.

Note: 9b966aae (mmc: sdio: fully reconfigure oldcard on resume) removed
the bus width reconfiguration since mmc_sdio_init_card already does it.
It is brought back now in case mmc_sdio_init_card is skipped.
