[Gta04-owner] [PATCH 1/2] mmc: core: use card->ocr when negotiating voltage setting in mmc_sdio_power_restore

As we are restoring power to a known card, it makes sense to use
the 'ocr' value known for the card rather than the generic one
for the host interface.
This matches the use of card->ocr passed to mmc_power_up in
mmc_sdio_runtime_resume  (just before mmc_sdio_power_restore is
called), and the value passed to mmc_sdio_init_card() a little
later in mmc_sdio_power_restore().
